Hazerswoude-Rijndijk is a village in the municipality of Alphen aan den Rijn, located in the province of South Holland. The area surrounding Hazerswoude was originally peaty and woody, and already contained some settlements in the Roman era. The settlement of Hazerswoude only originated in the 13th century, however, after the peat land was mined. Farmers dug out the peat soil and dried it until it became turf and could be used as a fuel. In the 16th century, the inhabitants started to cultivate tree nurseries, which gave the area an economic boost. When the surrounding area was drained in the 18th century, Hazerswoude became an important agricultural village with two centres: Hazerswoude-Dorp and Hazerswoude-Rijndijk.
Hazerswoude-Rijndijk is connected to Koudekerk aan den Rijn through a bridge. The village has a striking and unique water tower. The water tower of Hazerswoude-Rijndijk, which was designed by architect A.D. Heederik, dates from 1915, and is currently used as an office space. The tower is owned by Hoogvliet Beheer, part of the supermarket chain Hoogvliet.
