St. Alexander Nevsky Cathedral is a Bulgarian Orthodox cathedral in Sofia, the capital of Bulgaria. Built in Neo-Byzantine style, it serves as the cathedral church of the Patriarch of Bulgaria and it is one of the 50 largest Christian church buildings by volume in the world. It is one of Sofia's symbols and primary tourist attractions. It is among the 10 largest Eastern Orthodox church buildings and is the largest cathedral in the Balkans.
The construction of the St. Alexander Nevsky Cathedral started in 1882, when the foundation stone was laid, but most of it was built between 1904 and 1912. Saint Alexander Nevsky was a Russian prince. The cathedral was created in honour to the Russian soldiers who died during the Russo-Turkish War of 1877–1878, as a result of which Bulgaria was liberated from Ottoman rule.
The cathedral was designed by Alexander Pomerantsev, aided by Alexander Smirnov and Alexander Yakovlev, as the initial 1884–1885 project of Ivan Bogomolov was radically changed by Pomerantsev. The final design was finished in 1898, and the construction and decoration were done by a team of Bulgarian, Russian, Austro-Hungarian and other European artists, architects and workers.
The marble parts and the lighting fixtures were created in Munich, the metal elements for the gates in Berlin, while the gates themselves were manufactured in Karl Bamberg's factory in Vienna, and the mosaics were shipped from Venice.
The Alexander Nevsky Cathedral is a cross-domed basilica featuring an emphasized central dome. The cathedral's gold-plated dome is 45 m high, with the bell tower reaching 53 metres. The roof span of the central nave is 28 metres The temple has 12 bells with total weight of 23 tons, the heaviest weighing 12 tons and the lightest 10 kilograms. The interior is decorated with Italian marble in various colours, Brazilian onyx, alabaster, and other luxurious materials. The central dome has the Lord's Prayer inscribed around it, with thin gold letters.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
