01

Colosseum

Rome · Italy

Built in ten years, opened in 80, broken by the 1349 earthquake and quarried for centuries: the ruin you see today, placed on its real outline.

02

Leaning Tower of Pisa

Piazza del Duomo · Pisa · Italy

Two centuries of works on soft ground: the tower starts to sink in 1178, leans to 5.5° by 1990, and is pulled back to 3.97°.

03

Eiffel Tower

Paris · France

18,038 iron parts on four legs, from the caissons dug under the Seine to the 300 m top and its illumination.
