If you are interested in the Norwegian oil industry, a small part of its legacy is the leaning tower at Hinna Park south of Stavanger. During the 1980s, all of the largest offshore oil platforms was built in reinforced concrete. Norwegian Contractors was the world leader in building these platforms and to show their competence and skills in concrete slipforming of large constructions, this leaning tower was built in 1984. Seven years later, however, the glory days of Norwegian Contractors ended with a big bang, when the Sleipner platform sunk in Gandsfjorden in august 1991 when it was under construction. The company does not exist anymore, but the tower is still there and has become a symbol of the early days of the oil industry. The tower is 50 meters high and has varying diameter and thickness. Compared to its more famous counterpart, The Leaning Tower of Pisa which stands in an angle of 4 degrees this one has an angle of 16 degrees. At the top of the tower there is a 360 viewing platform with great view in all directions. In the center you will find an auditorium with 100 seats. In 2007 it was opened to the general public. Today the former yard area is developed into office buildings. It is also neighbour to SR-Bank Arena, the region´s main football stadium.
