In brief
The two Baltic cities display a common architectural language in public and residential buildings.
Useful to know
Stralsund and Wismar were associated with the Hanseatic League in the 14th–15th centuries. UNESCO highlights the development of brick Gothic in churches, town halls and housing. Later, the two cities also had a role in the Swedish administration of the region. [1]
The comparison is interesting because the style is not limited to religious architecture. The same material tradition can serve different public functions. When considering, separate the silhouette of the large church from the scale of the townhouse: the similar language does not eliminate differences in usage.
Don't just look for a repetition of a facade shape. Observe how the brick, the vertical accents and the layout to the street participate in the general nature of the environment. This is a proposed visual approach; the historical connection between the two cities is documented in their common listing as a world heritage site.
