Datacenter Wormer


Eenhoornweg 1
1531 ME


The 144-meter-high concrete radio mast has featured in the beautiful landscape along the Zaan since 1968. The Toren van Wormer, also known as the Nozema tower, has been in Cellnex’s possession since its acquisition in 2007. This telecom & data tower was one of the first five towers enhanced with a datacenter in a radio mast.

The radio mast has always been used for television, first analog and nowadays digital, and still serves this function to this day.
