KPN-toren

The KPN-toren is a telecommunications tower in Haarlem that rises approximately 150 meters and stands out in the industrial landscape. The structure was later repurposed as a data center that operates around the clock.

Construction began in 1967 and finished in 1968 as a telecommunications tower using advanced building methods. Since 2007, the tower has been converted into a data center with modern security systems.

Peregrine falcons nest high up on the structure and make it their home in the industrial area. The birds are a regular sight and have become part of what people notice about this building.

The structure is visible from various points in the industrial area and makes an impression on the skyline. Visitors can explore the surroundings and photograph it from different angles.

The structure requires exceptional precision in its engineering to keep equipment stable even during powerful winds. This technical achievement is not immediately obvious to visitors but makes the building a remarkable engineering feat.
