The Church of Saint Sophia in Ohrid is one of the most important monuments of North Macedonia, housing architecture and art from the Middle Ages.
The current church was built on the foundations of a metropolitan cathedral demolished in the first decade of the 6th century by the Barbarian invasions. The next church was built during the First Bulgarian Empire, after the official conversion to Christianity. Some sources date the building of the church during the rule of Knyaz Boris I (852 – 889). It was basically rebuilt in the last decade of the 10th century as a patriarchal cathedral in the form of a dome basilica, after the replacement of the capital of Bulgaria in Ohrid, during the reign of Tsar Samuil, when the church was the seat of the Bulgarian Patriarchate, an autocephalous Patriarchate. Later it became a seat of the Archbishopric of Ohrid, under the Patriarchate of Constantinople until the 18th century.
It was converted into a mosque during the rule of the Ottoman Empire. The interior of the church has been preserved with frescoes from the 11th, 12th and 13th century, which represent some of the most significant achievements in Byzantine painting of the time. The main part of the church was built in the 11th century, while external additions were built by Archbishop Gregory II in the 14th century.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
