Cityscape
The inner city of Cologne was completely destroyed during World War II. The reconstruction of the city followed the style of the 1950s, while respecting the old layout and naming of the streets. Thus, the city today is characterized by simple and modest post-war buildings, with few interspersed pre-war buildings which were reconstructed due to their historical importance. Some buildings of the "Wiederaufbauzeit" (era of reconstruction), for example the opera house by Wilhelm Riphahn, are nowadays regarded as classics of modern architecture. Nevertheless, the uncompromising style of the Cologne Opera house and other modern buildings has remained controversial.
Green areas account for over a quarter of Cologne which is approximately 75 m2 (807.29 sq ft) of public green space for every citizen of the city.
