There have been a lot of talks of people having interest in buying them and fixing them up to revive them over the years. But a lot of it falls flat generally due to the cost. It's a shame for sure, there are a lot of buildings around these former republics that are incredibly beautiful and historical, deserving of attention. But they just don't get it. In Tbilisi there are buildings in the city centre that are over 100 years old and just rotting. Culturally significant but just crumbling.
One building in the centre was demolished and replaced with a modern skyscraper which is just a hotel and casino. It's depressing.
