This paper discusses the urban planning history of an area in Saint Petersburg around the former Moskovskaya Zastava, a historical gateway that travelers passed through when approaching Saint Petersburg from Moscow. Specifically, we are interested in the architecture of the carriage building plant. By the end of the 19th century, this part of the city had turned into an industrial area, which saw dense development from 1897 to 1917. For the next one hundred years, this vast space did not see any transformations, constituting a complete, self-sufficient environment. The carriage building plant, originally constructed at the very end of the 19th century, remained standing near Moskovskaya Zastava until the early 21st century. In 2013, the industrial area ceased its existence, and the former carriage building plant was given for residential development.
