Datacenter Zwolle


Bergkloosterweg 62-I
8034 PP


In the radio mast of Zwollerkerspel, the analog antennas made room for Cellnex’s very first datacenter. On December 1, 2009, this datacenter was put into use by an accountants and consultancy firm with multiple offices in the Netherlands. The tower was never used for television signals, only radio frequencies were transmitted from Zwolle.

The tower stands in Zwollerkerspel, a former district in Zwolle, and was built around 1959.
