On the other side of the wooden bridge that I showed you in yesterday´s post is a drainage-mill (poldermolen in Dutch) called 'De Boezemvriend', that as one word could be translated as 'buddy' or 'soulmate' however in Dutch 'boezem' also means 'drainage canal' - so it's a pun.
The mill was built in 1871 to help pump water out of the polder to another level, the building next to it is a pumping-station. In 1990 the mill was renovated and is still operational today. On the grass an old wooden screw pump (vijzel or waterschroef in Dutch) is displayed; placed inside a mill and rotating it 'screws' the water up. They were a replacement for scoop wheels.
