“Tondo”是一座位于布鲁塞尔市中心的人行天桥，连接了比利时联邦议会的两座大楼。

‘Tondo’ is a footbridge that connects two buildings of the Belgian Federal Parliament in the centre of Brussels.

这座桥显然被设计为一个空间元素，而非一种技术解决方案。这座桥以文艺复兴时期的传统绘画 “Tondo”（圆盘画）命名，形状像一个环，悬挂在两座建筑之间。在这个封闭的外部空间中，宽敞的走道不仅是一条走廊，还兼具会议空间的功能。同时，“迂回”的设计使得两座建筑之间90厘米的高差被转化为一个4%坡度的斜坡，方便轮椅通行。

The bridge was explicitly designed as a spatial element, rather than a technical solution. Named after the tradition of the ‘Tondo’, a circular renaissance painting, the bridge is shaped like a ring, and suspended between the two buildings. A generous walk around an enclosed outer space is not simply a corridor, but also functions as a meeting space. At the same time, the ‘detour’ allows the height difference of 90cm between the floors of the two buildings to be bridged by means of a single, wheelchair accessible slope of 4%.

在城市的层面，这座桥遵循传统，作为一种“封闭”的元素存在，与叹息桥类似。桥身包覆镜面板，与建于18世纪的议会大楼外表面以及街对面新近加建的建筑相映成趣。在近处观察，玻璃开窗揭示了一个巧妙的视角看向连接两座建筑的这个通道。从结构上看，这座桥如同一张坚硬的唱片，它的地板悬挂在屋顶上，呈现了一种极简的结构形态：两座建筑之间一个转瞬即逝的临时构筑物。

Towards the city, the bridge shows itself as a ‘closed’ element, in the tradition of, for example, the Bridge of Sighs. Coated with mirrored panels, it reflects the 18th-century facade of the Parliament building and its recent addition across the street. Upon closer look, the glazed opening reveals a subtle view of the passages between the two buildings. Structurally, the bridge is a stiff disc, and its floor hangs from the roof with a minimal presence of structure: a near ephemeral pavilion between the buildings.
