The Prime Tower, also named "Maag-Tower" in an earlier stage of planning, is a skyscraper in Zurich, Switzerland. At a height of 126 metres (413 ft), it was the highest skyscraper in Switzerland from 2011 until 2015. The building is located near the Hardbrücke railway station. The tower replaces an industrial facility that has been demolished. According to its developers, the tower's construction, which took 15 years to plan and execute, was a financial success, with its valuation based on lease rates exceeding the construction cost by CHF 110 million. source: Wikipedia
