Landelijk Noord is the part of Amsterdam that is still farmland. Durgerdam, Ransdorp, Holysloot and Zunderdorp are dike villages in the peat country north-east of the IJ, inside the city boundary. Stand on the Durgerdammerdijk and the IJmeer is close to the top of the dike on one side, while the polder on the other side lies below it, with cows on it. Durgerdam is one row of low wooden houses along the old sea dike.
The ground here is drained peat, and by about 1300 the fields had sunk too low for a grain crop. The farmers put cattle on the grass instead and never took them off. The villages asked to be taken into Amsterdam on 1 January 1921, because they were poor. The First World War had ended their trade, a storm surge had flooded Waterland in 1916, and the fishermen could see that the Zuiderzee was about to be closed off from the sea. It was closed in 1932. So the villages you ride between now are places that stopped fishing, stopped growing grain, and kept the cows.
