The Folies were designed by the architect Bernard Tschumi for the Parc de la Villette in Paris. 

These metal structures are placed around the park, and take the form of red metal structures that stand out from a distance. While their square bases are all identical (10.8 metres per side), their shapes vary according to their purpose. Each Folie is identified by a name and a code composed of a combination of letters and numbers. 

This is a vibrational recording made with a Geofon from Folie L5, which has a walkway overhead and a tower with steps - we can hear the sound of children running overhead, and percussive knocks on the metal.
