The capital city of Boquerón Department in the Gran Chaco situated in western Paraguay is Filadelfia. The city, takes about 5 hours drive from the capital Asuncion, which is at the center of the Fernheim Colony.

In the year 1930 Filadelfia was founded by Russian Mennonites who flees from the Soviet Union. Filadelfia has set near the start of the Chaco War, although it was slightly affected. It became separated in the Second World War, with few of the German originally colonists sustaining the Nazis and then being expelled.

Currently the city is home to a library, a museum, a hospital and a radio station. The colony's villages located around Filadelfia, while some native reserves, house too much of the area's local population, from the Chulupí, Toba-Pilaga, Lengua, Ayoreo and Sanapaná groups. A modern superstore is situated in the centre of the city, which is the last shop to get groceries before going farther out to the Chaco. Mainly the town's filtered water supply is drained from underground cisterns and it replenished by alternating rainfall; the underground water is excessively salty to drink. A small memorial park known as Parque Trebol placed nearby 5 km (3 mi) to the east of urban. It now recognized as a place for guests to camp for the night.

The recently asphalted main road from Asunción continues earlier Filadelfia for an additional 70 km (40 mi) and runs away at the Mariscal Estigarribia, a military checkpoint. From this spot onwards, the highway to the border township fort General Eugenio A. Garay through Bolivia is about impassable.
