Wat Yanasen or Wat Yanusen is a Buddhist temple located on U-Thong Road towards the North of the city island called Koh Muang. It is a short walk from the famous Buddhist temple Wat Phra Mahathat in Ayutthaya. The exact date of the temple's construction is unknown, but some manuscripts mention that a Royal Treasury during the reign of the Ayutthaya Empire
Built close to this temple for keeping lassos and Holy ropes to control Elephants called 'Badhrope', the Main Chedi was built in the Ayutthaya period style with arched porches and indented terraces. The Ubosot, the main prayer room are the sites worth visiting in at Wat Yanasen. Unlike the main Chedi, the Ubosot is built in the early Rattanakosin period style.
Housing the temple's historical records restored during the Rattanakosin Period, the Ubosot has probably been constructed over earlier remains. Apart from this, there are a sermon hall and monk's quarters, which are present in every Buddhist monastery. This little known temple is the perfect place to visit in Ayutthaya if you are looking for some peace and calm.
