An ice hockey stadium built in Siberia by Russian billionaire Roman Abramovich for an estimated $150 million will now be demolished over safety concerns, 12 years after it was first opened to the public.

First inaugurated in 2007 in the Siberian city of Omsk, the arena was donated by Abramovich to the local Avangard Hockey Club in 2012. Last September, an evaluation of Omsk Arena’s structure determined the building was in “emergency condition,” with specialists finding structural defects in 90 percent of surveyed areas, including large cracks in its columns.
