Sơn Tây Essentials

Sơn Tây is defined by its 19th-century military history and traditional spiritual sites. The central Son Tay Ancient Citadel, constructed from local laterite, serves as the town's focal point alongside its adjacent military aircraft display. Spiritual life centers on Đền Và, a major shrine dedicated to the deity Tản Viên Sơn Thánh. For a glimpse into local commerce and culture, Chợ Nghệ offers a variety of regional goods, while the town's theatre serves as a hub for community performances.
