The Church of St Paraskeva is a Bulgarian Orthodox church in Sofia. The church, dedicated to Saint Paraskeva, is located on 58 Georgi Rakovski Street in the centre of the city. It is the third-largest church in Sofia.
Plans to build a church at the site date to 1910, when Stuttgart-educated Bulgarian architect Anton Tornyov (1868–1942) won a competition for the church's design. Due to the Balkan Wars and World War I, however, the construction was postponed. In 1922, the church board of trustees announced another competition, which was again won by Tornyov. The construction of the Church of St Paraskeva was complete by 1930, but the finishing works on the porticos did not cease until 1940.
St Paraskeva has a somewhat unusual design for an Eastern Orthodox church. For example, the cella is in practice a round chamber over 20 metres in diameter. The cella gradually disintegrates into the surrounding apses.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
