How good will it be if you can go back in time to explore all of Thailand, formerly called 'Siam', within one day? Ancient City or 'Muang Boran' Museum welcomes you to the world‘s largest private outdoor museum where you can discover all of Thailand's historical places. A visit to the Ancient City is comparable to a Thailand-round journey. On this 200-acre of land shaped like how the country looks on a map, you'll find many replicas of Thailand's important historical sites divided into 5 regions: the Northern, Northeastern, Central, Eastern and Southern regions. Learn the unique history and culture of each region, and explore many of Ancient Siam's highlights such as Ho Kham, The Phanom Rung Sanctuary, Dusit Maha Prasat Palace and The Stupa of Phra Maha That.
