The name of the neighborhood refers to Sant Gervasi de Cassoles, which was one of the parts of the former municipality of Sant Gervasi de Cassoles; and the Camp d'en Galvany urbanization which was begun in 1866 by its owner, Joseph Galvany Castelló.
The population of the neighborhood are mainly of upper class extraction and the oldest part is around the streets of Sagués i Amigó.
From the 1950s onwards numerous new buildings have been constructed, the most luxurious of which are to be found in Muntaner street.
Today it is a neighborhood with a lively nightlife due to the large number of bars, restaurants and nightspots, especially around Santaló and the surrounding streets.
