The heritage of the Roman Catholic St Peter's Church goes back long before this building was completed in 1733, with a number of churches standing on this spot for some 500 years before Giovanni Fusconi's superb Baroque designs were realised. Inspired by the great churches of Venice, much has been changed over the centuries, including Neoclassical additions following the 1895 earthquake and the construction of a new façade, complete with interesting fish details over the doors between 1938 and 1940 by the local architect Ivan Vurnik. Many changes have been made inside as well, including much work by Vurnik's wife, Helena. Points of particular interest include Franc Jelovšek's magnificent frescoes and several altar paintings by Valentin Metzinger.
