Few years ago, i went to Oslo and i discovered the wonderful Opera. I was amazed by the architecture and the view from the wonderful roof. The sloping roof of white marble overhangs majestically Oslo. The roof is in free access ; we can walk and admire the city and the fjord (“long, narrow and deep inlet of the sea between steep slopes”). Besides, the hall is magnificent with a corrugated hood wall and luminous bay windows.
