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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
