The Church of Our Lady of the Assumption (Nuestra Señora de la Asuncion), commonly known as the Santa Maria Church is the parish church of Santa Maria in Ilocos Sur province, Philippines. The church was designated as a UNESCO World Heritage Site on December 11, 1993 as part of the Baroque Churches of the Philippines, a collection of four Baroque Spanish-era churches.
The Santa Maria Church is an attraction to both tourists and Catholics in Ilocos Sur. It is not only a reminiscent of the four centuries of Spanish domination of that area but also a unique structure with a diversified architectural design of bricks and mortar. It was built on top of a hill not only as a lookout and a citadel but as a religious center during the early administration of the region by both the friars and soldiers of Spain.
