Brick Gothic in the strict sense is the name of a style of Gothic architecture widespread in Northern Germany, Denmark, Poland and the Baltic states, commonly identified with the sphere of influence of the Hanseatic League. It is also known as Baltic Brick Gothic or North German Brick Gothic and developed typical characteristics there. Gothic brick structures have also been erected in other regions, from England to Finland and Lake Peipus, but also in northern Italy, in southwestern and central France, and in the Danubian area of southern Germany. The particular architectural styles of these regions differ from each other.
Brick architecture became common in areas lacking sufficient supplies of natural building stone, such as the North European Plain, where traditional wooden constructions were found inadequate for monumental structures like churches, castles, or town halls. This was already the case in the 12th century, well within the period of Romanesque architecture. Some Brick Romanesque buildings have survived into the present time. The use of brick for major architectural features continued into the Renaissance period, so that also Brick Renaissance buildings are known. The transitions between the architectural styles are continuous.
The Brick Gothic style is characterised by the lack of figural architectural sculpture, and by its creative subdivision and structuring of walls, using built ornaments and the colour contrast between red bricks, glazed bricks and white lime plaster. Depending on trade connections and transport infrastructure (namely navigable rivers), architectural elements made from hewn stone might be added. Historically, techniques of building and decorating of brick originated in Lombardy.
