There are two church buildings in Koseze. The older structure, originally dedicated to Saint Margaret, is one of the oldest churches in the immediate Ljubljana area and dates back at least to the 14th century and the exterior has frescoes dating to the first half of the 15th century. A bell tower was added to the church in 1708, and the building was badly damaged in the 1895 Ljubljana earthquake. The church was repaired between 1907 and 1908. Ljubljana–Koseze became a parish in 1961, when it was separated from the Parish of Šentvid, and the church was rechristened as Divine Savior Church. The interior of the church was renovated by the architect Anton Bitenc (1920–1977) circa 1973. The medieval church was too small to serve the needs of the parish, and so a larger church was built next to it from 1972 to 1974. Dedicated to the Virgin Mary, this was the first church built in Ljubljana after the Second World War. The new church was designed by Anton Bitenc with extensive stained glass by Stane Kregar (1905–1973).
