context_page_description: The architecture of Germany has a long, rich and diverse history. Every major European style from Roman to Postmodern is represented, including renowned examples of Carolingian, Romanesque, Gothic, Renaissance, Baroque, Classical, Modern and International Style architecture.
  Centuries of fragmentation of Germany into principalities and kingdoms caused a great regional diversity and favoured vernacular architecture. This made for a heterogeneous and diverse architectural style, with architecture differing from town to town. While this diversity may still be witnessed in small towns, the devastation of architectural heritage in the larger cities during World War II resulted in extensive rebuilding characterized by simple modernist architecture.
context_section_description: The Roman Empire once extended over much of today's Federal Republic of Germany, and there are still remains from around 100–150AD  at the limes, the border defence system of Ancient Rome marking the boundaries of the Roman Empire. In addition to border fortifications such as forts and military camps, the Romans also built thermae, bridges, and amphitheatres.
  An important metropolis of that time was Trier, where the Porta Nigra, the largest Roman city gate north of the Alps is located, together with the remains of various thermal spas, a Roman bridge, and the (reconstructed) Aula Palatina.
  With the departure of the Romans, their urban culture and advances in architecture (e.g., underfloor heating, glass windows) vanished from Germany.
