The Sanctuary of Truth in Pattaya, Thailand, is an extraordinary architectural masterpiece that blends elements from Thai, Hindu, Buddhist, Chinese, and Khmer traditions. Initiated in 1981 by Thai businessman Lek Viriyaphan, this all-wood structure is a symbol of philosophical and religious unity, depicting important eastern religious concepts and the cycle of life. It remains unfinished, with construction anticipated to continue until at least 2025, but it's open to visitors who can explore its intricate carvings and sculptures.
