The question of preservation old buildings has been widely discussed in recent years.
Some people believe that old buildings have negative influence on modern cities` development while others claim that such buildings are priceless for science and history.
The first thing that should be noted is that old buildings are usually situated in cities` center; modern constructions are built around them.
It can be illustrated by Irkutsk city where city center looks like an outskirt of the town.
Narrow streets cannot be widen due to old buildings which take a huge part of this town.
Wooden houses with back yards take a valuable territory for modern buildings.
Additionally, old houses mostly belong to private owners who cannot afford new flats.
Hence, such kind of people, especially pensioners, cannot preserve their houses in original conditions.
Neither owners nor authorities take care about historical value of these houses and this irresponsibility affects the architecture of city in general.
On the other hand, these kinds of buildings are important part of national architecture, culture and history.
They are a reflection of the knowledge and experience of past generations.
In specific cases, some of these buildings have a significant scientific value.
In conclusion, I would say that old buildings should be preserved whatever the cost.
The authorities of cities should take additional measures immediately in order to keep them for next generation.
No doubt, modern cities should grow and develop, however they shouldn`t be built on the cultural heritage of the country.
