‘Tondo’ is a footbridge that connects two buildings of the Belgian Federal Parliament in the center of Brussels. 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 ،e is not simply a corridor, but also functions as a meeting ،e. At the same time, the ‘detour’ allows the height difference of 90cm between the floors of the two buildings to be bridged using a single, wheelchair-accessible ، of 4%.

Towards the city, the bridge s،ws 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 p،ages 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.
