A sprawling expanse of forests and fun, the Norwegian capital is one of the most attractive cities in the world. Many striking historical structures remain despite a devastating fire in the 17th century. Beautiful old buildings such as the Royal Palace compete with new creations such as the hugely impressive Opera House, an ultra-modern structure shaped like a glacier. On the outskirts of town lie stunning scenery and winter sports attractions, while the city streets are filled with eclectic restaurants, vast museums and trendy hangouts.
