Wat Lokkayasutharam

Wat Lokkayasutharam is a restored Buddhist temple ruin in Tha Wasukri Subdistrict, Phra Nakhon Si Ayutthaya, within the Ayutthaya Historical Park UNESCO World Heritage Site. It is renowned for its enormous outdoor reclining Buddha image, Phra Buddha Sai Yat, measuring about 42 meters long and 8 meters high, one of the largest in Ayutthaya. The temple's exact founding date is unknown but attributed to the Middle Ayutthaya period, with the Buddha restored in 1954.

Visitors can expect an open-air archaeological site dominated by a massive reclining Buddha image lying outdoors on a brick base, with the head resting on a lotus pedestal. The surrounding area contains ruined foundations, pillars, and remains of a former ubosot and viharn on flat, open ground with little shade. The site is quiet compared to central Ayutthaya temples, allowing for sightseeing, photography, and respectful observation of worshippers offering flowers and incense.
