Pyramidenkogel observation tower, Austria

The Pyramidenkogel timber structure in Keutschach (Carinthia, Austria) is 100 metres tall. This tower was built on a mountain ridge and is the world's highest viewing platform made of timber. Experienced EVVA partner Mailänder, based in Spittal, installed a particularly durable 3KSplus locking system.

Modern architecture and symbolism
The viewing platform is open to the public and offers a panoramic view (across several floors) of Carinthia's impressive landscapes, dominated by mountains and lakes. The Pyramidenkogel tower was planned by Klagenfurt-based architectural company Klaura Kaden + Partner in cooperation with the Lacker & Raml structural planners. Sixteen pillars made of laminated timber boards, supported by an elliptical steel frame make up the curved structure. The spiral shape of the tower symbolises growth and development. Inside, the centrally positioned glass lift is surrounded by a 120-metre-long slide. This is Europe's longest covered slide. Children in particular like to use the slide. It takes around 25 seconds to slide from top to bottom.

Security with foresight
The observation tower offers two exposed viewing platforms above the ten regular levels. The highest viewing platform is located almost 71 metres above the ground. The ninth floor has a weatherproof, glass sky box for holding events, for example. The Pyramidenkogel sits on an area spanning 700m². In addition to the tower, this area also includes a basic building with a foyer and ticket counter, a restaurant, a shop, restrooms and staff rooms. With 3KSplus (3-curve system) from EVVA, the building is secured with a reliable system which meets the highest security requirements. 3KSplus is ideal for locking systems with a number of different user groups. The system manages 50 people. EVVA's very own feature, the overlapping curve key cuts, guarantee optimum security. As a reversible key with unique rounded tip, the 3KSplus key is particularly easy to use. Patent terms run until 2025 and are intended to prevent unauthorised duplication of keys.

A total of 70 mechanical locking cylinders, in modular and two-sided locking designs, secure access in exterior areas as well as connecting and interior doors. The locking system can be extended at any time.
