Wat Rattanachai

Wat Rattanachai, also known as Wat Chin, is an active Theravada Buddhist temple located on the southern edge of Ayutthaya island in Phra Nakhon Si Ayutthaya District. Situated on U Thong Road near the Pa Sak River, it is notable for its association with the local Thai-Chinese community and its restored Ayutthaya-period architecture, including a prominent ubosot and chedi within a compact, accessible temple compound.

Visitors can expect a compact, active temple compound with an ordination hall (ubosot), a white chedi, Buddha images, and well-maintained grounds. The temple is located on the city island's southern road, surrounded by residential areas and close to the river. Visitors can walk around the courtyard, observe daily worship and merit-making activities, view traditional Thai-Chinese architectural details, and take photographs of the temple structures in a quiet, local setting.
