The museum also manages a number of legacy collections from famous artists of Herzegovina:
In addition to the above art collection items, the depot of the Museum of Herzegovina contains more than 400 art paintings, graphics, sculptures and objects. For the most part, these are works by local artists, works from guest exhibitions, as well as works created at the Art Colony "KOLO", which has been held in the Museum of Herzegovina Trebinje since 2015 (works by Beta and Risto Vukanović, Roman Petrović, Mića Popović, Vladimir Veličković, Jefta Perić, Tom Petrović, Virgilij Nevjestić...)
The permanent exhibition on Natural Riches of the Trebišnjica River Basin includes minerals, fossils, flora and fauna from the Trebišnjica river basin.
The museum Gallery is located on the ground floor and used for exhibitions, book promotions and readings, chamber music concerts, academic and professional seminars and other events, making the museum recognisable as a cultural and artistic meeting point open for visitors and providing cultural and educational content.
