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 Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
