La Tour aux Figures by Jean Dubuffet. Issy-les-Moulineaux

Newly renovated, this striking, interactive sculpture designed by artist Jean Dubuffet was completed posthumously, its creator having died during construction. Stood in all its abstract glory on a modest hill in Parc de L’île Saint-Germain, the construction dominates its surroundings with its irregular shape, bold colours and swirling design. Visitors can also explore the labyrinthine interior of the 24-metre structure.
