The city of Copenhagen dates way back to the 11th century when it received its first settlers. However, it wasn't until
Copenhagen was under the reign of Bishop Absalon (a Danish archbishop) in the 12th century that it began to receive more attention. A stone wall was put up in the 13th century to barricade the city as it rapidly grew in importance and became a center for trade.
