 Germany was not quick to adopt the Gothic style, and when it did so in the 1230s, the buildings were often modelled very directly upon French cathedrals, as Cologne Cathedral was modelled on Amiens.The smaller churches and abbeys continued to be constructed in a more provincial Romanesque manner, the date only being registered by the pointed window openings.The Romanesque period was a time of great development in the design and construction of defensive architecture.
