Filadelfia (Spanish pronunciation: [fi.laˈðel.fja]) is the capital of Boquerón Department in the Gran Chaco of western Paraguay. It is the centre of the Fernheim Colony. It is about a 5-hour drive from the capital of Asunción. With a population of about 20,000, it is the largest town for 400 kilometres (250 mi).
Filadelfia was founded in 1930 by Russian Mennonites who fled from the Soviet Union. Filadelfia lay near the front of the Chaco War, but was little affected. It became divided in the Second World War, with some of the original German colonists supporting Germany and later being expelled.
Filadelfia has developed into an important cattle herding settlement.
Today the town is home to a museum, a library, a radio station and a hospital. The museum displays objects from the town's Mennonite past, such as Russian overcoats, as well as the local wildlife, such as stuffed armadillos, anteaters, and toads. The colony's villages lie around Filadelfia, as do several native reserves, home to much of the area's native population, from the Chulupí, Lengua, Toba-Pilaga, Sanapaná and Ayoreo groups. A modern supermarket is located in the centre of the town, which is the last place to get groceries before heading farther out into the Chaco. Most of the town's potable water supply is drawn from underground cisterns, being replenished by intermittent rainfall; the underground water is too salty to drink. A small commemorative park known as Parque Trebol lies about 5 km (3 mi) to the east of town. It now serves as a place for visitors to camp for the night.
The newly asphalted highway from Asunción continues past Filadelfia for another 70 km (40 mi) and runs out at the military checkpoint Mariscal Estigarribia. From this point onwards, the road to the border town fort General Eugenio A. Garay with Bolivia is almost impassable.
