Standing guard imposingly, this neoclassical masterpiece, designed by Romanian architect Dimitrie Maimaroiu, was built in 1912 to serve the social, cultural and educational needs of the Romanian army. Banquets and official events are still hosted in the ballrooms, while the upstairs area is reserved for the army's library, as well as offices and classrooms for officer instruction. The main part of the building is off-limits to civilians, but the sumptuous restaurant and summer terrace is open to the public.
