Historic Centre of Warsaw

During the Warsaw Uprising in August 1944, more than 85% of Warsaw's historic centre was destroyed by Nazi troops. After the war, a five-year reconstruction campaign by its citizens resulted in today's meticulous restoration of the Old Town, with its churches, palaces and market-place. It is an outstanding example of a near-total reconstruction of a span of history covering the 13th to the 20th century.

The Historic Centre of Riga boasts the largest collection of Art Nouveau buildings in Europe. Between 1896 and 1913, the city expanded and a housing boom followed. The style which developed in Riga was influenced mainly by German, Austrian and Finnish architects. Mikhail Eisenstein is one of the most famous proponents of the style in Riga. 

After the revolution of 1905 a distinctively Latvian variation of Art Nouveau developed, known as National Romanticism. Architects started to use traditional Latvian folk elements and natural building materials. Typical elements were steep roofs, heavy structures and the use of ethnographic ornamental motifs. 

Riga as a city made its first mark in history in the 1201. In that year, Albert the Bishop of Bremen established his first German fortress here. With his Knights of the Sword he executed a Crusade to the Baltics. The town started to prosper as a trading station. This resulted in joining the Hanseatic League in 1282.
