The National Polytechnical Museum was established on 13 May 1957[4] by a Council of Ministers decree, initially under the Bulgarian Academy of Sciences.

Collections are supplemented by a library with more than 12,000 books and journals, and an archive of about 2,000 documents.

It became operational on 1 November 1900 and powered the tram system of Sofia, street lamps and several industries.

The station was declared a site of cultural significance in 1986, shortly after it ceased operations.
