The Holy Rosary Church (Thai: วัดแม่พระลูกประคำ, pronounced [wát mɛ̂ː pʰráʔ lûːk prā.kʰām]), also known as Kalawar Church (โบสถ์กาลหว่าร์, [bòːt kāːlāwàː]; from Portuguese: Calvario), is a Roman Catholic church in Bangkok. It is located in Samphanthawong District, on the eastern bank of the Chao Phraya River. The history of the church dates to 1769, when a group of Portuguese Catholics resettled in the area after the fall of Ayutthaya; the current church building, in Gothic Revival style, was built in 1891–97 on the site of two previous structures.
