Most Holy Trinity Church is the Roman Catholic parish for East Hampton and Amagansett on Long Island's South Fork (The Hamptons). Masses began to be celebrated here in the late 19th century, largely for the Irish immigrant population which worked on the estates. A church was built in 1896 and officially became a parish in 1907. In 2014 the parish serves a diverse community of year-round families, snow birds, and New Yorkers who spend weekends and summers here. We are still home to a growing immigrant community. The church is open all day for prayer. Come and visit us.
