Brief synthesis

Situated on the Gulf of Bothnia, Rauma is one of few medieval towns in Finland. The core of the town is , which is composed of some 600 buildings constructed of wood, most of which are privately owned, and covers an area of 29 ha. Originally situated at the seashore, the Old Town is located some 1.5 km inland from the present coastline due to land uplift. is both a commercial and a residential area comprising the town area within the toll boundaries of Rauma in the 19th century. The town plan structure of Rauma has been maintained since the medieval period, including the irregular street network, city blocks, plots of land and courtyards. The buildings are mainly one storey tall, and date back between the 18th and 19th centuries, while some cellars remain from earlier houses. The residential houses are placed along the street, and outbuildings such as former animal sheds and granaries are built around narrow courtyards.

The present appearance of the buildings is a result of phases of gradual changes and enlargements between the 18th  and the late 19th centuries. At the end of this period, the increased wealth of the town due to ship trading resulted in the extension and modernisation of residential buildings with decorative exterior panels with Neo-Renaissance details, and the characteristic, highly decorative gates of the courtyards.

The commercial area is located along two main streets stretching through the Old Town, while the Market Square, in the middle of the Old Town, forms the main meeting point and commercial place for local people and producers. The medieval church, built around a Franciscan monastery, and the former Town Hall built in 1775-76 in the Market Square are landmarks in the harmonious townscape of one-storey residential and commercial buildings.
