Above the compact Piran town centre reigns St. George's Cathedral, which gives the city its special character. It was probably built in the 12th century, but no exact data in this regard exists.
In the 14th century, it was built to its present size. In the year 1344, on the Day of St. George, the cathedral was consecrated by nine bishops from near and far. It acquired its present appearance after Baroque renovation in the year 1637. The Bell Tower was completed in 1608, and the Baptistery in the year 1650. During these years, reinforcements were made to the hill on which the cathedral rests.
The supporting walls were built in the year 1641, and on the sea side, the hill was fortified with stone arches. The construction of the stone arches began in the year 1663 and lasted until 1804. They were seriously dilapidated due to the effects of erosion, and thus had to be reconstructed and restored in 1998.
In the year 1737, St George's Cathedral acquired seven marble altars. Of the preserved works of art, the two sculptures of St. George are particularly worth seeing. The larger one is from the 17th century and is the work of an unknown sculptor. The smaller one is silver-plated and was made by a Piran-based goldsmith's workshop. The wall paintings are the work of the Venetian school. The two big paintings (Mass in Bolsena and St. George's Miracle) date from the beginning of the 17th century and were painted by Angelo de Coster.
References:The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
