Amsterdam has a long and eventful history. The origins of the city lie in the 12th century, when fishermen
living along the banks of the River Amstel built a bridge across the waterway near the IJ, then a large
saltwater inlet. Wooden locks under the bridge served as a dam; protecting the village from the rising IJ-waters,
which often flooded the early settlement. The mouth of the river Amstel, where the Damrak now is, formed a natural
harbor, which became important for trading-exchange from the larger koggeships into the smaller ships that sailed
the merchandise deeper into the hinterland.
