Inaugurated only in 2008, the Oslo Opera House has already become the landmark of the Norwegian capital. Its architecture intrigues. Like an iceberg floating in the Oslo fjord, locals and tourists alike climb it to reach its roof via soft inclines or explore its warm and modern foyer. Far from the elite image of most opera houses, the Oslo Opera House is an open space decisively. It has revolutionized its area, a former shipyard cut off from the rest of the city by an ugly highway that was forced underground, and made it a favourite promenade attracting recommendable neighbours like the new Munch Museum or the bar code urbanization project. The building fascinates, and the temptation of exploring its ins and outs only grows bigger as one approaches it.
