This museum is one of a kind. It houses the greatest world collection of royal coaches, dating from 17th Century to late 19th Century. The building itself is a “must see”, since it is in the old Royal Riding Arena of Belem Palace.

The most thorough and impressive gallery though, is from Cinla's website, Love is Speed: http://loveisspeed.blogspot.com/2012/08/the-national-coach-museum-is-located-in.html
