Ryazan's most famous site is probably the magnificent Dormition Cathedral. It was built between 1693 and 1699 by the architect Yakov Bukhvostov in the Naryshkin baroque style. In form it consists of a tall red brick structure decorated with carved white stone window frames and topped with five central domes.
Inside the cathedral has a towering iconostasis 27 metres in height which includes two miracle-working icons: the Our Lady of Murom Icon which dates from the 12th century and the Our Lady of Feodotievo which was discovered in the nearby village of Fedotievo in 1487. The cathedral is now the Summer Eparchial Cathedral of the Ryazan and Mikhailov Eparchy. It is only open in the summer.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
