The beginning of the museum work in Botevgrad was set in 1937 when a museum gathering was organized at the local high school. In 1952 the enriched and expanded collection was declared a state museum. As a result of long-term collecting work, several museum expositions were organized, the last one was opened in 1991. 

The museum fund, complete with original documents, photographs and objects, exceeds 15,000 items. From May 3, 2011, Botevgrad Historical Museum has been moved to the renovated building of the old courthouse.
