Datacenter Alphen aan den Rijn


Energieweg 4
2404 HE
Alphen aan den Rijn


Several of our telecom & data towers are breeding places for peregrine falcons, and that includes this tower in Alphen. Other towers that shelter these birds of prey are the tower in De Mortel, Zwolle and Haarlem. The 135-meter-high tower in Alphen in the only place in the Groene Hart (Green Heart) where the birds have settled down. They don’t occur anywhere else in the region.

After purchasing 24 towers/radio masts from KPN, Cellnex began establishing datacenters in these towers. In 2010, the datacenter in Alphen aan de Rijn was the second datacenter to be established.

Since December 22, 2017, the tower is permanently illuminated.
