Datacenter Hoogersmilde


Van Veenstraat 26
9423 VB


The telecom & data tower in Hoogersmilde was brought into use on November 24, 1959 and was named Zendmast Smilde. The construction has a height of 303 meter in total.

On the 50th anniversary of the tower in 2010, RTV Drenthe broadcast, among other things, a short documentary about the last couple of years and an hour-long recording of the construction on 1959.

In 2007, Cellnex purchased this tower – and 23 others in the Netherlands – from telecom company KPN. In April of 2015, a collaboration with CJ2 led to the tower being named CJ2 Datatoren.
