Tomsk is well known for its intricate "gingerbread" decoration of traditional wooden houses but the number of old homes in this style is decreasing.
Tomsk is one of the oldest Siberian towns and was founded in 1604.
A scattering of the iconic buildings still boasts brightly-coloured and cared-for exteriors with intricate wood carvings adorning window frames and roofs. The townhouses represent some of the finest examples of wooden architecture in the country.
There are around 2,000 of the historic houses in the city. A large number, however, look as if they have been abandoned. Their future is uncertain.
In 2016, a project was launched aimed at establishing a historic preservation zone in Tomsk within which the wooden houses could not be destroyed.
