Tarjishki (aka 'Strupeshki' because the name of the closest village of Strupets) Monastery St. Prophet Elijah is located in the northern part of the Gola Glava (Bald Head) hill in the Western Fore-Balkan, around 4.5 km western of village of Strupets. The monastery is built on the right bank of Iskar river - at distance around 300 meters from it.
It is still unknown when the old monastery was built, but after Bulgaria was conquered by the Ottomans, it was destroyed and later restored again. The monastery has an important role in the fight against the Ottomans. In these times it has nested Bulgarian heroes as Vasil Levski and Nikola Obretenov.Today the monastery is repaired and constantly active. The small one-apse basilica is located in the wide yard and is made of stone with dimensions of 4.95х7.39m. In 1991 next to the church was constructed a new temple.
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.
