Jardin des Boves

The Boves
The Boves, a well-preserved underground network of galleries 10 meters beneath the city, was built in the 10th century and can now be visited by tourists. The idea was to set up a vast underground network to make all inhabitant's cellars communicate by means of galleries. Excavation material (chalk) was not wasted but rather used to construct houses. During World War I and World War II, the Boves was utilized as an underground bunker to hide and protect residents and valued materials from falling bombs.

Brick Amsterdam

Buildings of the Amsterdam School are characterized by brick construction with complicated masonry with a rounded or organic appearance, relatively traditional massing, and the integration of an elaborate scheme of building elements inside and out: decorative masonry, art glass, wrought ironwork, spires or "ladder" windows (with horizontal bars), and integrated architectural sculpture. The aim was to create a total architectural experience, interior and exterior.
