This is a multicultural, noncommercial and nonprofit music event organized on the walls of the old fortress in the town of Niksic. The festival was initiated as an opportunity for affirmation of local bands to show their music and performances, but after only three years it went beyond the local character, so that it started gathering bands and performers from all over the region, with the growing popularity.

Its aim is to promote the fortress and cultural heritage of Montenegro in general, as well as to give opportunity to local and still not known performers to reach wider audiences. The festival places a particular emphasis on involvement of vulnerable groups – especially persons with disabilities.
