Ryazan Kremlin, the oldest part of the city of Ryazan, is one of the oldest museums in Russia. Located on the top of a steep hill, it is surrounded by rivers and a dry moat.
Human settlement on the territory of the Kremlin had occurred during the Mesolithic Era. Slavic tribes had colonized these places already by the 6th-7th centuries. Closest to the fortress of the future settlement of Borkovskoye, people on the island of Oka led an active trade with the Byzantine Empire, East and West.
In the 11th century Pereyaslavl-Ryazan Kremlin was a fortified castle, located in the highest, north-western part of the modern architectural complex on the site of the present church of the Holy Spirit today, an area of 2 hectares. Around the fortress were various suburbs, and numerous neukreplёnnye settlement in which the peasants, fisherman, and poor artisans lived. Streets were paved with wood, and yards were located close to each other. A princes' tower apparently stood on the site of the modern Dukhovskoy church.
The area around the city was occupied by vast forests, two natural barriers, and Trubezh Lybed to navigate. On the hill there were two lakes, Fast and Karasev, where in the event of a siege people could take drinking water. At one point, the rivers flooded, turning the Kremlin into an island.
Ryazan Kremlin is an architectural sight of the central historical part of the city. The Cathedral of the Assumption Cathedral and bell tower are designed so that their silhouettes can be seen from some distance in the city, and for him. From the 18th century to the first half of the 20th century, they were natural visual cues when navigating on the Oka River. In good weather, the spires and domes of the Kremlin can be seen far away from the city.
There are 8 churches in the ensemble, 6 in separate buildings, and 2 in public buildings.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
