The "renovation" was documented by Crimean activist, former chairman of the Republican Committee of the Autonomous Republic of Crimea for interethnic relations and deported citizens Edem Dudakov, who visited the site of the work, Radio Liberty said.

"The beams have been destroyed – they have been pulled from here, some have been sawed, some have been taken away. This means we will never have the beams back, although they themselves are an object of cultural heritage – they should have been preserved. And according to the UkrNIIrestoration [Ukrainian Research Institute for Restoration], it was necessary to replace only four beams, but they [the Russian firm] replaced all of them. This has an irreparable effect. We will never see the Khan's Palace you have seen it before," Dudakov said.

It is enough to switch on a computer and see who is working on this project – there are no experts in restoration there," former chairman of the restoration committee of the Department for the Protection of Cultural Heritage of Ukraine Yakiv Dikhtyar said.
