The municipality is characterized by many unique features, among which the Belene Danube archipelago, made up of 19 islands. Other interesting local features include the “Persina” Nature Park (the only such park set along the River Danube), the remains of the Roman military castle “Dimum” and the Belene Concentration Camp (which is the only partially preserved camp dating to the years of the Communist regime in Bulgaria). Belene is home to the largest Catholic community in Bulgaria, and is the only sanctuary in the country dedicated to the Bishop Eugene Bosilkov who was executed by the Communists on November 11, 1952, and was beatified by Pope John Paul II on March 15, 1998. Lastly, the city holds two sites of national importance: Belene Nuclear Power Plant and a Hydrotechnical Complex that features the country`s second bridge, stretching over the Danube. Overall, Belene Municipality has a wealth of natural, historic and cultural attractions.
