This covered gallery has a barrel vault of 12m diameter at a height of 16m. A row of columns supports a steel arched truss that is trussed every 4m. 21 purlins divide the semi-circle into 20 segments. The glass is divided into facets according to the segments and the panes are connected to each other in the form of scales. Small greenhouse profiles divide the glass into modules of about 1m. The entire steel structure is painted fire-resistant and the entire street is protected against fire by a sprinkler system. Smoke vents are placed at the highest point of the dome for smoke evacuation in case of fire.
