The local parish church , dedicated to Saint Leonard , belongs to the Roman Catholic Diocese of Novo Mesto . It was first mentioned in written documents dating to 1360 . The original structure was damaged in the 1511 Idrija earthquake and a new church was built in 1520 . It was surrounded by a double fortified wall with defensive towers to protect against Ottoman attacks , with granaries above and cellars below , and a single entrance accessed by a drawbridge over a moat . The internal wall was razed in 1844 and the rubble was used to build a schoolhouse . The external wall was lowered to the level of the cemetery wall in 1856 and then removed entirely when the cemetery was abandoned . The current church has a Baroque character built on a Gothic structure . Two chapels were added to the nave in 1720 and the interior of the church was reworked and refurnished in the Baroque style . The bell tower was increased in height , and towards the end of the 19th century it was outfitted with a neo-Gothic metal roof . The main altar is a high-Baroque wooden work ; an inscription indicated that it was created in 1764 by Franz Fajenz and Anton Kastelec , and renovated in 1865 by Leopold Goetzl . The side altars in the nave are in the Rococo style . The stone baptismal basin bears the year 1642 , and one bell dates from 1769 . Mozelj was elevated to a parish in 1509
