The Sanctuary of Truth Museum is an impressive wooden castle that stands over 100 meters tall, showcasing exquisite Thai architecture with a contemporary twist. Constructed without the use of a single nail, it's built from sturdy hardwoods that can bear significant weight, including golden teak, padauk, redwood, and thitpong. This architectural marvel was created during the reign of King Rama IX and seeks to break away from traditional Thai architectural confines by embracing ancient construction techniques. Joinery methods such as mortise and tenon, wooden pegs, and dovetail joints have been expertly applied in its creation. The museum's primary concept is to present the beliefs, faiths, religions, philosophies, ethics, and the admirable cultures of East Asian people. At the heart of this magnificent structure lies the central hall, home to the grand Buddha Vihara. This intricately carved wooden masterpiece symbolizes the emptiness of the universe or Nirvana, providing visitors with a profound insight into the spiritual and cultural heritage that it represents.
