Prostora is a new non-profit project led by architect Marcela Steinbachová, the founder of the Skupina Studio, Kruh Association, and the Director of its activities (its lecture series on architecture, the Architecture Day festival, and the Film and Architecture festival, as well as publication releases). Prostora is located on the 1st floor above Náměstí Míru Square, in the former telephone exchange building at Blanická Street 9. The gallery's name is derived from the more commonly used synonym for the word 'space,' but it defines a more delimited, bounded environment, in this case, an exhibition space.
