Paris glass pyramid.
Paris council has unveiled plans for a 50-story glass pyramid after voting to drop a ban on high-rise buildings.
Proposals for the Project Triangle, designed by Swiss architecture practice Herzog & de Meuron who designed the Olympic stadium in Beijing. The tower will have offices, a conference center, 400-bedroom hotel and restaurants and cafes. It will be surrounded by parks, gardens and shops. The building is planned to be around 590 feet high which will make the third highest building in Paris. The tower will run on solar and wind power and is set for completion in 2012.
