Banya Bashi Mosque is a mosque in Sofia, Bulgaria. The mosque was designed by the famous Ottoman architect Mimar Sinan and completed in 1566, during the years the Ottomans had control of the city. The mosque derives its name from the phrase Banya Bashi, which means many baths. In the Turkish language Banyo means bath and Baş (pronounced Bash) means 'head' or 'main', so looking at the location it is built on, a more logical translation of the name would be 'Head of the bath mosque'. The most outstanding feature of the mosque is that it was actually built over natural thermal spas; one can even see the steam rising from vents in the ground near the mosque walls. The mosque is famous for its large dome, diameter 15m, and the minaret.
Currently, the Banya Bashi Mosque is the only functioning mosque in Sofia, a remnant of the Ottoman rule of Bulgaria that lasted nearly five centuries, and is used by the city's Muslim community.
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.
