Ayutthaya’s Viharn Phra Mongkol Bophit houses an immense 17m high sitting Buddha, made from brick and plaster and covered with bronze 3-4 inches stick. The Buddha is 12.45 metres high and his lap is 9.55 metres wide. Damaged and then repaired when the original viharn collapsed in the 18th century, this giant Buddha stood in the open for the next 200 years. One of the largest in Thailand, it was sculpted, according to the site guidebook, in 1538 at Wat Chichiang.
