Museum Siam (Thai: มิวเซียมสยาม) is a discovery museum that is located at Sanam Chai road in Bangkok, Thailand. The museum was established in 2007 in the former building of the Ministry of Commerce. It was created to teach the national identity and history of the people of Thailand, and their relationships with neighboring cultures. The motto of the museum is “Play + Learn = เพลิน” (which means 'joyously' in Thai); through a series of interactive exhibits, the museum shows the development of Thailand from the past to present.
