Oswalt told news agency DDP he feels there remains a “drive to physically erase the regime of injustice,” adding that efforts continue to remove traces of socialism in many formerly East German city centres.
This urge is a mistake, according to Oswalt.
Just a few months before the 20th anniversary of the fall of the Berlin Wall, pre and post-war modern architecture is judged unequally in what was East and West Germany, he said.
The quality of architecture in the communist German Democratic Republic (GDR) may be difficult to ascertain, and only the passage of time will reveal what Germany has felt worthy of preserving.
During the post-war era, modern architecture was an unquestioned symbol of a better, progressive Germany – but today's Zeitgeist ignores this wholesale, he said.
He also criticised GDR architecture from late in the communist country's existence, saying that the late 1960s and 1970s showed a departure from innovative and high-quality building as economic pressure and industrialisation took over.
Oswalt's criticism comes ahead of a major exhibition opening in Berlin on Wednesday to celebrate the 90th anniversary of the revolutionary Bauhaus movement, which inspired many aspects of modern architecture.
