这栋木质结构的观测塔，以一种独特的形式实现了观测者与自然景观的交流。观测塔内置的巨大镜子，让其中的每一个人都能享受周围的美丽景致。观察者可以拾级而上到达观测平台，欣赏周围的美景，或者站在观测塔底层，通过内部观测镜享受别样的观景体验。
The Periscope Tower is a giant wooden periscope structure that serves as an observation tower and engages the viewer in a dialogue with the landscape. With the help of a large mirror the Periscope Tower makes it possible for everyone to enjoy the views of the surrounding landscape. One can either climb up the stairs to enjoy the view over the lake and into the surrounding landscape from the viewing deck, or simply stay on the ground and get the view through the periscope mirror.
▼观测塔全貌，full view
观测塔位于Seinäjoki临近市中心的人工湖边，这片位于山顶的人造湖水 Lake Kyrösjärvi设计之初是为满足三个主要功能：帮助控制Ostrobothnia平原的洪涝灾害，为Seinäjoki城市提供必要的电能供应，增加湖边新社区的吸引力。这里即将建造120000平方米新住宅区，可容纳2000人居住。观测塔项目是湖岸景区再造计划的一部分，由OOPEAA公司为Seinäjoki 房屋交易会开发建造。
The Periscope Tower is situated on the shore of a man-made lake that has been built on top of a hill in the vicinity of the center of the city of Seinäjoki. The man-made lake, Lake Kyrösjärvi, has been created in order to serve three main functions: to help keep the flooding in the plains of Ostrobothnia under control, to generate energy for the electric power plant serving the city of Seinäjoki, and to form an attractive site for a new residential area to be constructed on the shores of the lake. 120 000 square meters of new housing will be built there to provide homes for about 2000 people. The Periscope Tower is part of a larger landscape design project for reshaping the lakeshore, developed by OOPEAA for the Seinäjoki Housing Fair 2016.
▼全木质结构观测塔，the periscope is made entirely of wood
观测塔为全木质结构，包括一个内部核心交叉复合木材和一个外部木质框架支撑结构。由交叉复合木材制成的内部核心形成了超大的潜望镜框架，楼梯环绕中心而设。当观测者循着楼梯上下移动时，便可以在各个层面的开口中享受不同的风景。
Made entirely of wood, the building is composed of an inner core of cross-laminated timber (CLT) and an external wooden frame that serves as a load bearing structure. The inner core made of CLT forms the frame for an extra large periscope with stairs circling around it. When taking the stairs up or down one can experience a rich range of different views framed by the various openings cut into the structure.

该塔由三个预制构件组成，屋顶作为第四个构件。立面及楼梯间由松木制成。一些细节及安全围栏采用钢材。项目的设计宗旨是简单高质的木结构建筑，为当地社区提供观景娱乐及知识普及作用。
The tower is composed of three prefabricated elements with the roof forming a fourth element. The facades and the stairs are made of larch. The details and the security netting are of steel. The idea was to create a simple wooden structure of high quality in a way that supports learning and reflects a commitment to empowering and strengthening the local community.

随着观测塔的建立，项目的主旨是刺激人工湖周围的各项建设工程，并力图将这片区域变为集休闲娱乐和社区居住的全新生活区，为居住在这个城市中的人提供服务。这里将成为在建中的新社区乃至全程的休闲娱乐胜地。观测塔由Seinäjoki市政府委任，SWECO及SEDU（当地建筑建造职业学校）合作实现。项目为2016年Seinäjoki市年度芬兰住宅交易会而建，并将持续向所有居民开放。
With the Periscope Tower, the aim is to activate the dam around the man-made lake and to turn it into a recreational area serving the residents of the new neighborhood to be constructed there as well as others living in Seinäjoki and the region at large. It will be connected to a broader network of recreational paths designed to be accessible to everyone.The Periscope Tower was commissioned by the City of Seinäjoki, realized in collaboration with SWECO Seinäjoki and constructed by the students of SEDU, a local vocational school for building and construction skills. It is part of the area developed for the annual Finnish Housing Fair to be held in Seinäjoki in 2016. The Periscope Tower will remain open to the public to enjoy also after the fair closes.

这谁翻译的啊？一点都不专业
在中国，得收费才可以进入。。。。
收不收钱也是排长队全是人
你生活在上世纪吗？进个公园要收费的年代？一个塔而已。
我觉的楼主没活在上世纪，而你是活在未来，象这种建筑，建在中国，不可能免费给你看的，要不收费进入，要不特权进入，再就是直接锁上让你只能在外面看看不让进去，反正就是不会让你随便进的；除非是有领导来看，应付完了再关掉
你也不看看中国多少人芬兰多少人，不收费后期维护你出钱吗？平时公园里不是固定的东西基本不可能存在太久的，卫生纸都给你拿掉。
