Copenhagen’s controversial new opera house has been inaugurated. The 336-million euro project, funded by a billionaire shipping magnate, has attracted mixed reactions. The smiles at the opening covered over the reported disputes between the owner and architect. It is reported the architect was close to quitting halfway through the construction, but agreed to make structural changes, rather than put the project at risk. The new opera house, which measures 41,000 square metres, can seat as many as 1,700 people. As well as the main stage, the centre houses five side and back stages.
