Wat Pho is one of the largest and oldest wats in Bangkok covering an area of 50 rai or 80,000 square metres. It is home to more than one thousand Buddha images, as well as one of the largest single Buddha images at 46 metres (151 ft) in length. The Wat Pho complex consists of two walled compounds bisected by Chetuphon Road running in the east–west direction. The larger northern walled compound, the phutthawat, is open to visitors and contains the finest buildings dedicated to the Buddha, including the bot with its four directional viharn, and the temple housing the reclining Buddha. The southern compound, the sankhawat, contains the residential quarters of the monks and a school. The perimeter wall of the main temple complex has sixteen gates, two of which serve as entrances for the public.
