In the basement, there are 40 models that IBM made from Leonardo's sketches and drawings, including a helicopter,[10] as well as some 3D animations about the Italian master's inventions, allowing the public to see them working. In the park is a pigeon house from the middle of XVth century built by Etienne le Loup, Amboise beadle that can shelter up to a thousand birds. In 2003, Jean Saint-Bris set up an educational and cultural course in the park of the Clos Lucé with several sound terminals and impressive machines inspired from Leonardo's mind.
