The teritory of the commune of Trebinje  population 36,000; height above sea-level 274 m ) lies predominantly in the valley of the river Trebisnjica in the ambience of Southern Hercegovinian karst, on the strip of land dividing the district of karst lakes from Adriatic Sea.

Today Trebinje is the cultular and business centre of the ecologically blameless and resourcefully still unexploited eastern part of Herzegovina.

The most ancient human habitations in the district of Trebinje date back to early paleolithic. Archaeologists have registred the cultural levels 40,000-odd years old. Especially interesting is thet the cultural continuity in this region has been never ceased to this very day. Along with paleolithic sites there are numerous dwellings and different finds from both the age of neolithic and the later stocks of civilization and culture. In the times of antiquity this part of Herzegovina, with Illyrics indwelling here, was exposed to the influences of diverse peoples, in particular Greeks and Romans. First Christian communities were formed here as early as in the 1^st century AD.

Later on, in the Middle Ages ( posterior to the period of Byzantine domination, when the realm of Trebinje was a separate archont-dom )., Travunija was, together with Hum, the legal and political antecedent of Herzegovina, forming part of Serbian and later Bosnian state. The multi-centenary Turkish rule, lasting from the second half of the 15^th unto the second half of the 19^th century was relieved by a special patronage and then by full administrative control by Austria-Hungary. Half the century later, from the end of the First World War this region composed part of Kingdom of Yugoslavia, and from Second World War until 1991. it was integral part of SFRY. After the Civil War in Bosnia and Herzegovina 1992/1995 Trebinje and Herzegovina have been a constituent part of Republic Serb.

In one legacy, there was noted testimony that there was not a Serbian house from which one could not arrive to some monastery on foot, before the night. The monasteries are things which exist and which will newer die out...                                                  DETAILS>>>

The climate in the walley of Trebinje is a modified Mediterranean. It is graced by very many hours of sunlight, low relative humidity and overcast, intense air streams, rains in the winterly season and long, hot summers. There the sun shines 260 days yearly (7 hours daily) in Trebinje. These skies are not only marked by sunny summers ( only 2 clody days in August) but as well the sunlit winters (only 6 cloudy days in Janyary). Equally interesting is that in Trebinje the automn is far and away warmer than the spring (mean temperature 15⁰ C). The mean monthly temperatures rise to: January 5.2, March 8, July 24, August 24.4, December 7⁰C. 

Hydrographically, due to heavy amount of rainfall, the commune of Trebinje and the whole of Herzegovina have an abundance of ground and overland water currents. Large portion of this richness in water was used in the construction of HET hydro-electric scheme producing the highest output of electricity in the Republic Serb, another portion, serving to interconnect all main Herzegovinian waters into a system beginning to come to fruition in the mega-project“GORNJIHORIZONTI” (“TheUpper Horizonts”).

Next to electrical industry ( here is the home of the Electricity Authority of Republic Serb ), the largest facities currently in Trebinje have the business from the metallic complex ( especially tool industry, producing a wide range of tools for metalworking industry ). Fairly large facilities also have agriculture ( Mediterranean crops, healthu food), woodworking, textile, telecommunication, tourist, commercial, construction, information and the media, and other industries.
