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.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
