“美国景观大师劳伦斯·哈普林设计的波特兰系列广场（Portland Open Space Sequence）将八个城市街区的更新项目融合为由起伏台地、林荫道、小径和形式独特的喷泉构成的连贯空间，成为该市公共集会的中心地点。系列广场通过建筑物之间的小路将人们引向不同的景致，犹如一个中枢神经系统，调节着城市在不同季节的功能活动，同时也展现着平等主义的特征：从各个方向上对所有人开放。波特兰系列广场从任何意义上说都是一个里程碑式的存在，它的成功为当下和未来的从业者树立了典范。”
– 2021年评审委员会

“Lawrence Halprin’s Portland Open Space Sequence transformed eight blocks of urban renewal into a sequence of pastoral rolling berms, tree canopies, allées, and an exclamatory fountain that has become the central locus of public gathering for the city. Drawing people in through pathways between buildings that culminate in a quartet of landscape moments, the Sequence becomes connective tissue: a central nervous system that pulses with life year-round and with an egalitarianism found in its accessibility to everyone from all directions. This is a landmark in every sense, and its success has set a standard for both current and future practitioners.”

项目概述
PROJECT STATEMENT

波特兰系列广场是1963年至1971年期间，波特兰市在摩尔特诺马、考利茨、克拉克马斯和大隆德邦联部落规划的四组景观，包含一系列互动喷泉、广场和连接路径。这些修建于上世纪中期的现代市政资产在国际上享有盛誉，亦是波特兰市最具影响力的景观作品。

系列广场的设计初衷是丰富公民的娱乐生活，它始于一个“残酷”的开端：为了重新开发场地，波特兰最古老的社区之一（South Portland）和另外一块民族聚居的土地遭到了强行“抹除”。凭借大胆的艺术性和文艺复兴以来从未有过的、极富凝聚力和生命力的公共空间，系列广场打破了美国城市主义和上世纪中期形成的现代主义惯例。其设计和建造改变了美国城市空间的历史，开辟了一条从被动的公园和广场转变为更具活力和参与性的、融合自然、艺术与社会实验的公共空间的新道路。作为社区自豪感的源泉，系列广场已经成为波特兰市中心的灵魂，喷泉区的独特地标，太平洋西北地区的自然主义代表案例，以及可供几代人享受的“人民之地”。

The Portland Open Space Sequence is a quartet of interactive fountains, plazas, and connecting pathways designed between 1963 and 1971 on native land home to Multnomah, Cowlitz, Clackamas, and Confederate Tribes of Grand Ronde. These mid-century modern civic assets are internationally celebrated and stand as Portland’s most influential works of landscape architecture.

Designed to foster civic joy, the Sequence emerged from brutal beginnings, a redevelopment that erased an ethnic enclave and one of Portland’s oldest neighborhoods, South Portland. With bold artistry and magnetic, exuberant public spaces not seen since the Renaissance, the Sequence defies the conventions of American urbanism and mid-century modernism. Their design and construction changed the history of American urban space, pioneering a path from passive parks and squares to a more dynamic, participatory merging of nature, art, and social experiment. A source of community pride, the Sequence, has become the soul of the downtown, iconic Fountain District landmark, a symbol of the Pacific Northwest naturalism, and ‘people place’ for generations to enjoy.

PROJECT NARRATIVE

创造公共空间的传统

五十年前，《纽约时报》建筑评论家Ada Louise Huxtable在波特兰见证了前院喷泉（Forecourt Fountain）的开放——这在后来被她称作是“自文艺复兴以来最重要的城市空间之一”。前院喷泉是一个每分钟流量为1.3万加仑的瀑布水景，这在以前的任何城市都从未出现过。那是一个关键性的时刻：和美国当时的许多城市一样，波特兰的市中心也正面临着“逐渐走向荒凉”的困境。

行事向来低调的Huxtable对波特兰提出了一项颇为惊人的挑战：作为一个被大自然包围的城市，充分发挥其成为“梦想世界都市”的潜力。而事实证明，这个想法是精准而正确的。前院喷泉（后更名为伊拉·凯勒喷泉）是为波特兰专门打造的四个喷泉广场之一，它标志着波特兰市中心乃至美国公共空间复兴的开始。

作为一项独特的文化财富，波特兰市中心的系列水景广场已被列入国家历史遗迹名录，并于2017年获得文化景观基金会（TCLF）颁发的管理卓越奖。2020年，俄勒冈州美国建筑师协会为波特兰系列广场授予学院奖，以表彰其对俄勒冈州建筑环境的重大贡献。

波特兰的城市复兴

与美国许多其他内陆城市一样，波特兰市中心在二战之后迅速走向衰退。居民们纷纷迁往新开发的城郊，市区商店的消费者也逐步流向了区域性的购物中心。曾经充斥着居民、工人和购物者的市中心建筑，要么经年失修，要么干脆被清空，作为停车场使用。

随着1949年颁布的《联邦住房法案》为“清理平民窟”提供了大量拨款，波特兰也得以迎来一系列形式大胆的城市更新项目。该市共确定了11个需要清理和重建的区域，并在1958年以微弱优势赢得了投票倡议。随后，波特兰发展委员会（PDC）正式成立并接手相关工作。南礼堂项目（South Auditorium Project）是第一个开始建设的项目。

南礼堂区因其北部边缘修建已久的公民礼堂而得名，这里曾经是一个以犹太人为主的社区，拥有五座活跃的犹太教会堂。然而，郊区的喧嚣正在令其付出代价。尽管这里仍然充斥着热闹的熟食店、酒吧和裁缝铺，还有不断涌入的来自意大利、希腊、爱尔兰和罗马的移民人口，但根据PDC开展的研究显示，该区域的385栋建筑中，有62%未达到合格标准。到1962年，54个城市街区被征用以进行重新开发，1500多居民被重新安置。PDC利用1200万美元的联邦资金对土地进行了清理，并将地产公开招标，最终吸引到了一个由当地投资者组成的财团。与此同时，PDC做出了一个重要决定，即聘请自己的景观设计师，为该区域设计一系列的开放空间，以此来为公共领域划定新时代的发展方向。

喷泉区

水源喷泉（Source Fountain）是波特兰市最小的水景广场之一，同时也是系列广场的首个空间。它的形式呼应了溪流从山丘流向低地的不同阶段，因而被当地人亲切地称为“烟囱”，象征着源源不断的泉涌。

爱悦（Lovejoy）广场占地一英亩，与南边水源喷泉的极简设计和北边充满沉思氛围的Pettygrove公园形成了对比。公园周边的植被被保留下来，而在广场内部，活跃的喷泉模仿了附近喀斯特山脉的天然瀑布与奔腾的溪流，并最终汇聚在平静的水池中，邀请游客参与一整段神奇的冒险。“这座喷泉巧妙地捕捉了俄勒冈州溪流的精髓：水从上层水池的边缘倾泻而下，在一系列不规则的台阶上溅起泡沫，随后又流入平静的下层低地。”《俄勒冈人报》（7.28.66）”

Pettygrove公园是一系列开放水景空间的中心，葱郁茂盛的植物是其最大的特点。公园中分布着几处景观小丘，数条小路蜿蜒在其周围。公园的平面展现了自然主义理念，模拟了木兰、榉树、山茱萸、美国甜木、红橡树、枫树、欧洲栗、欧洲山毛榉和普通山毛榉的林地环境。在中心位置，一个大型的舞台式广场被弧形石墙所包围。东南侧设有一个低矮的圆形反射池，池中有一个阶梯状的基座，此处立有Manuel Izquierdo打造的黄铜雕塑 “梦想者”（The Dreamer）。覆盖于地表的英国常春藤（Hedera helix）、草坪以及在特定区域种植的日本冬青灌木（齿叶冬青）与茂盛的树冠形成相辅相成的关系。

长廊对于系列广场而言是不可或缺的存在。它们提供了从公共街道进入广场的路径，并持续吸引着路人。建筑物的后退程度与树木和植被的界线保持了一致，能够起到平衡视野和周围环境的作用。

系列广场的北部边缘是备受欢迎的前院喷泉（Forecourt Fountain），它占据了一整个街区，且可以俯瞰东侧的凯勒礼堂。公园的中央是一个造型独特、由分层钢筋混凝土砌筑的喷泉，跌水高度达到25英尺（7.62米）。瀑布底端是一个平坦的直线型下沉水池，一系列钢筋混凝土板允许游客从水池上方进入。该广场还设有一系列混凝土台阶，就像是舞台空间一般，让公民生活变得更加丰富多彩。

波特兰与城市公共空间的复兴

就在前院喷泉建成的前几天，俄亥俄州国民警卫队向抗议越南战争的手无寸铁的肯特州立大学学生开火并造成4人死亡。几天后，在反战抗议活动最为激烈的阶段，波特兰警方又与波特兰州立大学的抗议者发生冲突，27名学生被送往医院。因而，前院喷泉的洗礼仪式氛围十分紧张，尤其是当一群年轻学生聚集在广场上的时候。就在警察的严厉注视下，景观设计师拿起了话筒，说道：“这些直截了当的人，某种程度上对城市理解得最深。”他向城市的官员们挥了挥手，“所以，当你在花园里玩乐的时候，请试着记住，我们大家全都聚集在这里。”说完，所有人都欢呼雀跃着跳进了喷泉，并且很快开始手拉着手在水池里跳舞。

波特兰系列广场一经刊登，便立刻成为全世界景观设计师的朝圣地。当美国其他城市中心的活动还停留在办公、购物和停车的时候，波特兰系列广场已在邀请人们进行纯粹的娱乐。

五十年来，波特兰人一直贯彻着这种娱乐精神，并不断创造出更多的公共空间。1967年，即爱悦广场开放的两年后，“Riverfront for People”在威拉米特河的西岸举办了一次具有代表意义的野餐，这场活动为其后来将Harbor Drive公路改造成Tom McCall滨水公园的行动（1978年）揭开了序幕。

到了1990年代，波特兰对自然的城市形态以及戏剧性的公共空间的追求已经成为常态，在此期间，另一个相互连接的系列水景广场也在河区建成。波特兰系列广场最终开启了一项跨越50年的传统，即建设根植于自然形式的、具有戏剧感和互动性的公共空间。

保护和修复

具有开创性的公私合作关系在过去十年间形成，旨在全年不间断地为系列广场提供保护、修复、维护和激活。2014年，来自当地的景观设计事务所受托重新恢复系列广场的设计意图并为之赋予新的活力。

我们同在一起

为了确保系列广场的50周年纪念活动在疫情期间顺利进行，景观团队与多位当地艺术家进行了合作，共同创造了一场虚拟体验，以强调系列广场的宝贵价值和对数代人产生的积极影响。通过新闻、社交媒体和限制距离的艺术/文化表演，波特兰系列广场最初的设计意图所展现的愿景与美，以及它为社区乃至世界带来的环境与社会价值均得到了彰显。

PROJECT NARRATIVE

Creating a Tradition of Public Space

Five decades ago, New York Times architecture critic Ada Louise Huxtable witnessed the opening of what she called “one of the most important urban spaces since the Renaissance” – in Portland, Oregon. The place was Forecourt Fountain, a 13,000- gallon-per-minute cascade of water the likes of which no city had seen before. The time was a critical moment when the downtown was teetering on the brink of the ﬁnal slide toward the desolation suﬀered by many American cities of the era.

Never one for hyperbole, Huxtable’s challenge to Portland to raise to its potential for a “dreamworld urbanism” of a city nested in nature, proved well-placed. As the ﬁnal in a sequence of four fountain plazas designed for Portland, Forecourt (later renamed Ira Keller) Fountain, indeed, marked the beginning of the renaissance – for both downtown Portland and American public space.

A unique cultural treasure, the innovative series of downtown Portland fountain plazas, has been listed in the National Register of Historic Places. The Cultural Landscape Foundation (TCLF) recognized the Sequence and the Conservancy with the 2017 Stewardship Excellence Awards and the Oregon American Institute of Architects bestowed its 2020 Fellows Awards for the Sequence’s significant contributions to the built environment in Oregon.

Urban Renewal in Portland

Like many American inner cities, downtown Portland rapidly fell into decline after WWII. Residents took ﬂight to new suburbs while regional malls drained shoppers from downtown stores. Older downtown buildings, once bustling with residents, workers and shoppers either fell into disrepair or were simply cleared for more parking.

With the Federal Housing Act of 1949 providing generous grants for “slum removal,” Portland optimistically looked to bold new forms of urban renewal. The city identiﬁed 11 areas to be cleared and built anew and by a narrowly won ballot initiative in 1958, created the Portland Development Commission (PDC) to do the job. First project: the South Auditorium Project.

Named for the Civic Auditorium long standing at its northern edge, the district had once been a predominantly Jewish neighborhood with ﬁve active synagogues. But suburban ﬂight was taking its toll. Though it still boasted a lively collection of delis, bars, and tailors plus a rising population of Italian, Greek, Irish and Roma immigrants, the PDC conducted studies showing 62 percent of its 385 buildings to be substandard. By 1962, 54 city blocks were condemned for redevelopment relocating more than 1,500 residents. With $12 million in federal funds, the PDC cleared the land and put the property out to bid, ultimately luring a consortium of regional investors. Simultaneously, PDC made a fateful decision, by hiring its own landscape architect to design the sequence of open space for the district and setting a course for a new era of public realm.

The Fountain District

One of the smallest in the city and the first of a series for the Portland Open Space Sequence, depicting stages of a stream as they pass from the mountains to the lowlands, the Source Fountain is affectionately referred by locals as the Chimney, representing an artesian spring.

The Lovejoy, one-acre plaza serves as a counterpoint to the minimalist Source Fountain to the South and a contemplative Pettygrove Park to the North. Vegetation is kept at the park’s perimeter, while within the plaza, an active fountain mimics the natural waterfalls and rushing streams of the nearby Cascade Range, culminating in quiet pools that invite visitors to partake in adventures. “The fountain wonderfully captures the spirit of Oregon’s streams. Pouring in a sheet over the lip of the upper pool, the water is whipped into a foaming cascade as it splashes down over an irregular series of stairsteps and then out again into a placid lower basin.” (The Oregonian, 7.28.66)

While distinct in verdant character, the Pettygrove is the center park in the sequence of outdoor fountain rooms. It consists of paths meandering along landscaped hillocks featuring a now dense canopy. The plan is naturalistic, simulating clumps of trees within a woodland setting of Magnolia, Zelkova, Dogwood, American Sweetgum, Red Oak, Maples, European Chestnut, European and Common Beech. Toward the center, a large stage-like plaza is framed by the Rocky Butte curved stone walls. At the southeast is a low circular reflecting pool with a stepped pedestal featuring brass sculpture “The Dreamer” by Manuel Izquierdo. Complementing the tree canopy is a ground cover of English Ivy (Hedera helix), lawn, and in select areas, Japanese holly shrubs (Ilex crenata).

Integral to the Sequence is the series of promenades that provide access from the public streets into the District drawing in the pedestrian. The building setback is consistent with the lines of trees and plantings that balance views with surroundings.

Anchoring the Sequence’s northern edge, a full city block, is the beloved Forecourt Fountain Park, overlooks the Keller Auditorium to the east. The park’s centerpiece is a dramatic tiered reinforced concrete fountain with 25-foot waterfalls. At the base of the waterfalls is a sunken flat rectilinear pool with a series of reinforced concrete pads that allow access over the pool as well as a series of concrete steps – stages for choreography of civic life.

Portland and the Renaissance of Urban Public Space

Only days before Forecourt Fountain’s dedication, the Ohio National Guard ﬁred on unarmed Kent State University students protesting the U.S. war in Vietnam, killing four. Days later, clashes between Portland Police and protesters at Portland State University sent 27 students to the hospital during the city’s most violent antiwar protests. The mood at Forecourt’s christening was tense, especially when a cadre of young students collected around the plaza. But as police sternly looked on, the landscape architect grabbed the microphone, “These very straight people somehow understand what cities, can be all about,” waving hands towards the city oﬃcials. “So, as you play in this garden please try to remember that we’re all in this together.” And with that, all rejoiced jumping into the fountain and soon people were holding hands and dancing in the pools.

Published throughout the world, Portland Sequence instantly became a pilgrimage site for landscape architects. Built at a time when American inner cities only oﬀered places to work, shop and park, the plazas invited a radical new activity: play.

For five decades, Portlanders have continued to play in their public spaces and creating more of them. In 1967, just two years after the opening of Lovejoy, Riverfront for People held a symbolic picnic on the Willamette River’s western bank, kicking oﬀ what would become their successful eﬀort to turn a highway known as Harbor Drive into what in 1978 became Tom McCall Waterfront Park. In 1982, after holding an international design competition, Portland connived its new living room – Pioneer Courthouse Square.

By the 1990s, the city’s embrace of urban forms of nature and theatrical public space had become a norm, building another sequence of interconnected fountains as the spine of the River District. Ultimately, the Portland Open Space Sequence has launched a 50-year tradition of building theatrically interactive public spaces rooted in the forms of nature.

Preservation & Restoration

A groundbreaking public-private partnership to restore the Sequence was formed within the last decade preserving, restoring, maintaining, and activating the Sequence year-round. In 2014, a local landscape architecture design studio was commissioned to restore the design intent and renew vitality of the Sequence.

We Are All In This Together

To mark the 50th anniversary milestone amidst uncertainty of COVID-19 pandemic, we teamed up with local artists to create a virtual experience celebrating the heritage and positive impact of the Sequence for generations to enjoy. Through press, social media and non-public socially distance art/cultural performance was held on-site to commemorate the vision and beauty of the original design intent as well as environmental and social value the Sequence brings to the community and world.
