The City of Warsaw (Old Town) Like so many other European cities, Warsaw owes its origin to a river, in this case, the Vistula. A small river port and a ford over which a bridge was soon built were the elements around which the first population center arose in the Middle Ages. Excavations within the present urban perimeter have revealed as many as three earlier settlements. The oldest, Stare Bródno, flourished during the 10th and 11th centuries, but was destroyed in the harsh feudal struggles of the time. It was replaced by the Kamion enclave, which existed as early as 1065, and this in turn by the Jazdow enclave, the oldest records of which date back to 1262. Some decades later, it was decided to move Jazdow to a site offering better defensive possibilities. A river terrace was chosen on the left bank of the Vistula, about 3 km north of Jazdow, on which there was a small village called Warszawa, exactly where the Stare Miasto, the old town of Warsaw, is situated today.
