We visited the Winter Palace and were reminded once again of the tremendous influence on the interior that Scotsman Charles Cameron made. He was the main architect to Catherine the Great of Russia who reigned from 1762 until she died in 1796. She acquired all the best painting, had the most lavish interiors and gold leaf was used extensively in creating some of the most striking interiors you would find anywhere.
The picture shown is of a pavilion created by Charles Cameron. You can read about him at the following link:
