The sumptuous and luxurious Crimson Drawing Room.
Acquired in 1732 by Frederick Prince of wales, completely remodelled by Henry Holland and Sir John Nash for George Prince of Wales and Prince Regent, Carlton House, described at that time as the most beautiful house in England, was demolished in 1829, which is very regrettable obviously, but replaced with Carlton House Terrace, a magnificent architectural ensemble by Sir John Nash.
In those times, when beautiful and important buildings were demolished, they were replaced with... beautiful and important buildings, and not with concrete monsters and steel and glass boxes as it has been the case during those last six decades!
Anyhow, beautiful and important buildings should not be demolished at all! It is a crime! A crime against Architecture, Art, Culture, History, Civilization and National Identity!
