Immeuble Clarté is an apartment building in Geneva designed by Le Corbusier and Pierre Jeanneret starting from 1928 and built in 1931-32. It has eight storeys and comprises 45 free plan units of diverse configurations and sizes. It is one of Le Corbusier's key early projects in which he explored the principles of modernist architecture in apartment buildings, which later led to the Unité d'Habitation design principle.
After it escaped demolition in the 1960s, the building was first renovated in the 1970s. After being again threatened with demolition in the early 1980s, in 1986 it was listed as a historic monument. In July 2016, the building and several other works by Le Corbusier were inscribed as UNESCO World Heritage Sites.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
