Human settlement on the territory of the Kremlin  had occurred during the Mesolithic Era.. Archaeological excavations indicate large settlements in the territory of modern Fefёlovo Bora Kanishchevo, neighborhoods in Borki and Fisherman's streets. 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. The second major settlement was a fortified fort named Borisov-Glebov. Later, it became Pereyaslavlskoy residence of bishops, and then known as the area of Borisoglebskaya. Large clusters of settlements in the area, as well as  the presence of a large commercial port has necessitated the construction of a fortified city to protect the population and the surrounding area. This city became Pereyaslavl-Ryazan. Foundation of the city. The date that Kremlin Pereyaslavl-Ryazan was founded is listed in the Psalter, and today is stored in the Museum-Reserve 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.
