Oerlikonturm, Observation tower in Oerlikon, Switzerland.

Oerlikonturm is a 35.50-metre concrete observation tower in Oerliker Park, with its viewing platform at 33 metres, inaugurated in 2001. The whole tower is wrapped in a fine-meshed steel net. Around a blue-dyed concrete core, 203 steps arranged in a circuit lead to a first platform, from which a final spiral staircase of 13 steps reaches the viewing platform.

The City of Zurich built this observation tower in 2001 as a joint project between its Parks and Public Works departments. The structure was created as part of the broader development of public space in this district.

The tower functions as a landmark within Oerlikon Park, drawing people who seek a vantage point over the city. Visitors gather there to share views and connect with the landscape around them.

Visitors need to climb about 200 steps around the central core to reach the viewing areas, which requires some endurance. Comfortable shoes are recommended, as the stairs are narrow and the platforms have limited space.

The tower's entire exterior is wrapped in a fine-mesh steel net, so the concrete structure reads as a translucent blue cylinder from outside. The blue colour comes from dye mixed into the 30-metre concrete core, not from paint. A final 13-step spiral staircase leads from the first platform to the top.
