The National Art Gallery houses over 50,000 pieces of Bulgarian art. It is located on Battenberg Square in the capital city of Sofia, occupying most of the historic and imposing edifice of the former royal palace of Bulgaria.

The gallery has been established in 1934 and moved to the palace in 1946, after the abolition of the monarchy.

The royal palace is a typical example of Second Empire architecture with chateauesque connotations, was constructed in two stages, the first lasting between 1880 and 1882 during the rule of Knyaz Alexander Battenberg and the second stage, during Knyaz (later Tsar) Ferdinand.
