Defense Architecture – is an initiative developed by BACU – Birou pentru Artă şi Cercetare Urbană (Bureau for Art and Urban Research). The Defense Architecture project was launched in 2014 by B.A.C.U. Association in order to protect 19th and 20th century military architecture in Central and Eastern Europe and other regions. One of the main goals of our project is to identify buildings that served defense purposes in wartime or were designed to defend cities and towns. Another goal is to rehabilitate war memorials. The objective of the project is an interactive map that would display the most valuable examples of defense architecture in Romania, such as the fortification system surrounding Bucharest and the Focsani-Namoloasa-Galati Fortified Region. These batteries, forts, defense structures, monuments were erected from 1882 to 1916. In the first phase of this project we will concentrate on the analysis / research / study, followed by the second phase, when we will elaborate regulations and will deal with education of local authorities and inhabitants of those protected areas, through a legislative program concerning the architectural stylistics of the military structures erected in 19th and 20th century.One of the lines of action taken by the Defense Architecture project is to initiate classification procedures – as provided by Law no. 422/2001 on the protection of historical monuments – so that one fort and three batteries from the Bucharest fortification system are included on the Historical Monuments List. B.A.C.U. Association has taken steps to include the Bucharest fortifications in the Historical Monuments List, to clarify the legal situation for a number of them and to make them functional, by including the most representative ones in the tourist and cultural circuit.
