After I took a number of photos of the hanging plant columns of the Basel Museum of Culture (during our visit at Thanksgiving), I turned my attention to the courtyard around them — the Schürhof — the floor of which is largely a set of low, wide steps descending to the museum lobby and gift shop.
Before the museum was renovated in 2011 by Herzog & de Meuron, the Schürhof* was not open to the public. The museum shared a door with the Museum of Natural Sciences around the corner.
Looking at a “before” photo (here, fourth image), the old courtyard appears to have been used at least partly as a parking lot.
The renovation excavated it to open up a new museum entrance in the base of the existing 1917 neoclassical building.
The other buildings that enclose the Schürhof are medieval.
Above and below are three views from upper windows inside the museum.
