The head of preservation group Arkhnadzor is calling for tougher penalties for developers who illegally demolish buildings, Interfax reported.
Developers should be prohibited from continuing a project if their work is illegal, Arkhnadzor chief Konstantin Mikhailov said last week at a meeting of the commission for the protection of cultural heritage sites.
He said the recent increase in fines for illegal construction work was insufficient.
"In January alone, we had five cases of illegal demolition of historic sites," he said.
Moscow Deputy Mayor Marat Khusnullin said the city was preparing measures to fight the problem.
