At the beginning of the 20th century, the city of Ålesund was rebuilt in the Art Nouveau style, influenced by styles of France. The 1930s, when functionalism dominated, became a strong period for Norwegian architecture. It is only since the late 20th century that Norwegian architects have achieved international renown. One of the most striking modern buildings in Norway is the Sámi Parliament in Kárášjohka, designed by Stein Halvorson and Christian Sundby. Its debating chamber, in timber, is an abstract version of a ''lavvo,'' the traditional tent used by the nomadic Sámi people.
