The Sanctuary of Truth at Pattaya, Thailand is a magnificent architecture. The temple is made entirely of wood without any metal nails.
Lonelyplanet says, “It is best described as a visionary environment: part art installation, religious shrine and cultural monument. Constructed in four wings dedicated to Thai, Khmer, Chinese, and Indian religious iconography.”
The ornate temple-like complex was conceived by Lek Viriyaphant, a Thai millionaire who spent his fortune on this and other heritage projects (such as Ancient City near Bangkok) that revived and preserved ancient building techniques and architecture in danger of extinction. In this case, the building continues to support hand-hewn woodworking skills as it’s been under construction since 1981 and still isn’t finished. –Source: Lonelyplanet
