A popular architectural trend at the turn of the 19th century was Art Nouveau. The style embraces and harmonizes flowing and elegant lines both inside and out. A good example is the Palace Hotel. The property opened along the edge of City Hall Square in 1910. The architect, Anton Rosen, was extraordinarily meticulous. He not only crafted a marvelous building but then designed such minute details as the furniture, staff uniforms and even the room keys. It is now owned by Scandic Hotels.
