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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
