Oldehove Tower

The Oldehove a leaning and unfinished church tower in the medieval centre of the Dutch city Leeuwarden. The height of the tower is 39 metres.
The top of the tower is displaced horizontally 2 metres from the centre. One can climb the tower for €3.50

The leaning tower of the unfinished church is one of the landmarks of the Frisian city.
