The Round Church is a large partially preserved early medieval Eastern Orthodox church. It lies in Preslav, the former capital of the First Bulgarian Empire, today a town in northeastern Bulgaria. The church dates to the early 10th century, the time of Tsar Simeon I's rule, and was unearthed and first archaeologically examined in 1927–1928.
Considered to be one of the most impressive examples of medieval Bulgarian architecture, the Round Church takes its name from the distinctive shape of one of its three sections, the cella, which is a rotunda that serves as a place of liturgy. The church's design also includes a wide atrium and a rectangular entrance area, or narthex, marked by two circular turrets.
The church has been likened to examples of religious architecture from the late Roman (Early Christian) period, the Caucasus, and the Carolingian Pre-Romanesque of Charlemagne because of its characteristic plan, which is significantly different from contemporaneous Bulgarian or Byzantine buildings. The church's alternative name, the Golden Church, stems from its possible and popular identification with a 'new golden church' in Preslav referenced in a medieval literary source.
The Round Church's rich interior decoration, which makes ample use of mosaics, ceramics and marble details, distinguishes it from other churches in Preslav. Its interior features hundreds of drawings depicting ships, fauna, and Christian figures. Medieval inscriptions on the walls range from names of saints in Byzantine Greek to separate letters and short texts in the Glagolitic and Cyrillic alphabets.
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.
