Wat Tha Sai

Wat Tha Sai, or the Monastery of the Sand Landing, is a restored ruin situated on Ayutthaya’s city island in the Tha Wasukri Sub-district. The restored ruin is located along U Thong Road on the premises of Wat Racha Praditsathan, as it is today considered part of the latter's premises.

Wat Tha Sai was located next to the mouth of Khlong Pratu Khao Pluak, which once separated it from Wat Racha Praditsathan (on the opposite side of the canal). This canal has been filled in, for the most part, leaving a small pond on the premises.

Traces of the Pratu Khao Pluak fortress and the watergate Pratu Khao Pluak can still be seen in situ. Khlong Pratu Khao Pluak, or the ‘Canal of the Gate of Unmilled Rice’, was part of a waterway running through the middle of Ayutthaya from north to south. The canal, a shortcut in the oxbow of the Lopburi River, ran until the Chikun Bridge and continued to the Chinese water gate (Pratu Jin).
