It is composed of nine villages: Breazova, Bulza, Coșevița, Coșteiu de Sus, Groși, Margina (commune seat), Nemeșești, Sintești and Zorani.

Margina is located in the eastern extremity of Timiș County, 8 km (5 mi) east of Făget, and is crossed by the Bega River.

The wild boar (Sus scrofa) is quite widespread in the forests of the commune, it descends for food to the vicinity of households and causes significant damage to wheat and corn fields.

In the forest and meadows also live: woodpeckers, white wagtails, hazel grouses, little owls, eagle-owls, sparrows, etc.

[6] In the Middle Ages it played an important role in the area; here there was a fortress, first mentioned in 1439 and disputed by the lords of the time.

In 1658, as a result of the political interests of Ákos Barcsay, Margina was ceded to the Turks, who ruled it for 30 years.

At the end of the 18th century, Germans and Hungarians settled here, brought as officials or workers in the vinegar factory, one of the largest in Europe at that time.
