Wat Si Sawai

Wat Si Sawai is an ancient temple in the central zone of Sukhothai Historical Park in Mueang Kao, Mueang Sukhothai District, Sukhothai Province, Thailand. Notable for its three well-preserved Khmer-style prangs built of laterite, it was originally constructed as a Hindu shrine in the late 12th to early 13th century during Khmer influence and later adapted for Theravada Buddhism. Enclosed by a laterite wall, it is one of the oldest monuments in the UNESCO World Heritage park.

Visitors can expect a compact, walled temple compound featuring three tall, corncob-shaped Khmer prangs set on a shared laterite base, surrounded by a laterite enclosure wall and moat traces. The prangs show stucco details and Hindu-influenced lintels. The site is open and grassy with paved paths, located near other central zone ruins. Visitors explore on foot or by bicycle, viewing the exterior architecture and courtyard. Interpretive signs explain the Hindu origins and later Buddhist use.

Wat Si Sawai was originally built as a Hindu shrine in the late 12th to early 13th century during the Khmer Lopburi period, likely dedicated to Shiva, before Sukhothai became an independent kingdom. Its three prangs in Khmer style predate most Sukhothai-style monuments. Later, during the Sukhothai Kingdom in the 14th century, it was adapted for Theravada Buddhism with the addition of a viharn. It is part of Sukhothai Historical Park, inscribed as a UNESCO World Heritage Site in 1991.

The temple illustrates the transition from Khmer Hindu influence to Sukhothai Theravada Buddhist architecture. Its prangs, lintels depicting Hindu deities, and later Buddhist modifications reflect the cultural and religious layering of the Sukhothai period. As a key monument in the central zone, it is valued for its architectural heritage and role in understanding early Sukhothai art and religion.
