The Czech National Library of Technology is located at Technická 6 in Prague 6. The building also houses a branch of the Municipal Library of Prague. The former site of the National Library of Technology was the Clementinum in the Old Town of Prague, from which all books and materials were moved to the library's current location after completion of the current building in 2009. The building was designed by architects Roman Brychta, Adam Halíř, Ondřej Hofmeister and Petr Lešek of Projektil Architekti after winning first prize in an architectural competition held in 2000.
