On the wall around the Dusit Maha Prasat is Aphorn Phimok Prasat Pavilion, a lovely little pavilion in typical Thai style, built by King Mongkut (King Rama IV) as a disrobing pavilion. In the old days the King was carried on a palanquin to the shoulder-high step of the pavilion where he alighted and removed his ceremonial hat and gown before proceeding to the Dusit Audience Hall. This pavilion was reproduced by King Chulalongkorn (King Rama V) at Bang Pa-In Summer Palace and a replica of it was exhibited at the World Fair in Brussels in 1958.
