A detailed guide to the architectural details of former revenue houses, “Carefully Washed,” by local historian Ksenia Sidorina, who has been washing and restoring St. Petersburg's tiles, stoves, and stained-glass windows since 2019 with a team of volunteer restorers called Geng.
The book is the most comprehensive compendium of metlach and tile stamps in Russian, as well as a guide with which you can safely go walking around St. Petersburg in search of already washed stained glass windows, stoves, ceramic floors and walls.
