Visit Wat Mahathat Worawihan
Wat Mahathat Worawihan which local people call Wat Na Phrathat or Wat Phra Si Rattana Mahathat is an old Temple, situated on Khao Ngu Road, Tambon Na Mueang in Mueang Ratchaburi municipal area. It is believed that this temple was built in the Dvaravati Period, around the 10th -11th Century, nearly the same time as when the old city of Ratchaburi was built. Since then, the temple has gone through several periods from Dvaravati to Khmer to Ayutthaya, which is reflected by the diverse architectural style of the principal stupa.
The principal stupa, which is over 24 m high, and its 3 surrounding stupas are very well maintained you can walk around the temple or even climb up to the prayer room inside the principal prang and pay respect to the site. There is not a whole lot of people around when I was there and I found it to be quite peaceful to walk around and observe all the little details on the stupas. The temple is open from 6 AM to 5 PM and it is free to enter.
