There are some 400 temples in Bangkok. Most are done in classical Bangkok era architectural style.
Thai temple is an open public institution.
People wonder in and out of temples at will. The devotes come to pray in front of the principal Buddha image at all times, except when the monks hold their daily prayer. The students come to seek a peaceful place to study the textbooks. Taxi drivers stop in the spacious temple ground for a quiet snooze. Visitors are therefore welcome to look in, if interested, at anytime, provided of course that they are attired and observe propriety as they might visit their own churches.
