The exact origin of the name of the mountain Trebević is unknown, but it is assumed that in the area of ​​this mountain there was once an altar dedicated to one of the Slavic gods, probably Perun, so the word “trebevište” (from trijebiti) remained. However, there are indications that the ritual of sacrifice dates back to the Illyrian era, when animals were sacrificed in numerous sinkholes near the top of the mountain. During the old century, the slopes of this mountain were inhabited by the Illyrians, who also founded a settlement in the area of ​​today’s Debelo brdo. After the ancient period, the importance of Trebević declined in the middle ages, while during the Ottoman rule it grew thanks to increased urbanization on its northern slopes. During the Austro-Hungarian rule, the importance of Trebević grew rapidly, primarily from the military aspect, because the entire city could be seen from its slopes. Due to that, fortifications were built on certain elevations, the remains of which can be seen to this day. In addition to the military, the importance of Trebević as a picnic area is growing, and then its slopes begin to be forested, and trails for hikers are arranged for the purpose of recreational tourism.

During the Kingdom of Yugoslavia, the importance of Trebević as a picnic area grew with the establishment of the first mountaineering associations in Sarajevo, and the first mountain lodges were built in its area. After World War 2, the reconstruction of existing and new tourist capacities began. For easier access, a cable car was built from the city center to the Vidikovac area. New promenades were built, as well as mountain lodges and resorts that were destroyed in the 1992-1995 war. Trebevic hosted bobsled and sledders during the XIV Winter Olympic Games, which took place in Sarajevo in 1984, so it remained inscribed in the books of the International Olympic Committee as a sports facility.

The cultural and historical heritage of the protected landscape “Trebević” includes the astronomical observatory Čolina Kapa, ​​in fact the Bistrik Tower fortress where the observatory building was added, and the remains of the Draguljac fortress and the Austro-Hungarian waterworks Bistrica – Hrid.
