Wat Pho
The city's largest wat has what is perhaps the most majestic representation of the Buddha in Bangkok. The 150-foot reclining Buddha---carved from brick and stucco, then covered with black lacquer and a final layer of gold---is so large it fills an entire viharn. Especially noteworthy are the mammoth statue's 10-foot feet, with the 108 auspicious signs of the Buddha inlaid in mother-of-pearl. Behind the viharn holding the Reclining Buddha is Bangkok's oldest open university. A century before Bangkok was established as the capital, a monastery was founded here to teach traditional medicine. Around the walls are marble plaques inscribed with formulas for herbal cures, and stone sculptures squat in various postures demonstrating techniques for relieving pain. The monks still practice ancient cures, and the massage school (now outside the temple grounds on a nearby street, though massages are still available in the temple) is world-famous. Thai massages (which can actually be painful, though therapeutic) cost around B400 for 1 hour. Appointments aren't necessary—you usually won't have to wait long if you just show up. Massage therapy courses of up to 200 hours are also available at the school.
