Devaraj-Kunlai Gate is a museum for the royal coaches that were used by Kings Chulalongkorn (Rama 5), Vajiravudh (Rama 6), Prajadhipok (Rama 7), Mahidol (Rama 8), and Bhumibol (Rama 9, the current king.) There were five coaches on display, all of which were made in England. The ones used by the king in formal processions are painted yellow while those used by other members of the court or for private transport are black.
