Kolomna is one of the most ancient cities of the Moscow region. The city arose on the picturesque high bank of the Moskva River at the confluence of the Kolomenki River into it. The founding of the city was chosen very successfully: the merging of the rivers of Moscow and the Oka was a crossroads of the most important water trade routes.
The official date of the foundation of the city in the national historiography is considered to be 1177, in which Kolomna first mentioned the Laurentian Chronicle as an existing outpost of the Ryazan principality at the crossroads of waterways - the Kolomenka, Moscow and Oka rivers.
