Tucked away at the side of CastleCourt shopping centre sits Belfast's first Roman Catholic Church. St. Mary's was built in 1784 and, in those early days of ecumenicalism, partly funded by the Presbyterian Church and Church of Ireland. Inside are two Italian paintings, ornate frescos and a domed colonnade. Outside the 1954 Our Lady of Lourdes Grotto features a stained-glass window commemorating the church's role in sheltering evacuees from the 1956 Hungarian Uprising.
