Filadelfia (also called Colonia Fernheim) is a Mennonite colony in the Chaco region of Paraguay. It is different from most of Paraguay; this is due to the remote location and harsh environment, and also to its majority of German immigrants (coming by way of the Soviet Union). The first foreign people moved in during the 1920s, and the town was finally founded in 1930. Their economic basis is agriculture, in particular dairy cattle farming and peanuts. The Mennonites still speak German (Plattdeutsch), but Spanish is spoken as readily. The Fernheim Cooperative  is responsible for many aspects of life in the colony.
The Mennonite Fernheim cooperative runs many private services, like hospitals, schools, etc., which are paid for by the profits from agriculture. Nearly all of the Mennonite families have shares in the co-op. Outsiders can buy in, subject to living one year among the community so your character can be judged. 10% of your earnings are submitted to the co-op as well. In return, you get use of all their facilities, and benefits like health insurance (not provided by the Paraguayan government). You may also get share dividends from the co-op, but they will sometimes hold votes on whether to retain the dividends and invest them in new facilities. Members get discounts at the co-op supermarket, also. The co-op does provides services for non-members, such as schools for the indigenous. You can learn all of this and much more, such as local history, at the museum.
Water is constantly an issue in the Chaco; all households collect their rainwater. It is processed and stored for use, so water is safe to drink in Filadelfia. Filadelfia began desalinisation of ground water recently, as rainfall was low. Power is supplied by Itaipu dam; previously, it was generated locally by burning wood. Population is growing 4% per year, while demands on power grow 20% per year, as affluence increases. The colony produces 5 main agricultural goods: Castor beans (for hydraulic oil), cotton, sorbum (for biodiesel), sesame and peanuts.
Most businesses are closed during lunchtime from 12am to 2pm, as well as on Saturday afternoon and Sunday.
The town is rather small, and all the interesting and important places are within easy reached on foot - note, however, that the heat can be punishing, so walk slowly and bring water. Blocks are very long. There are pickup truck taxis; you can choose to ride on the back or in the cab. Other public transport is unheard of.
Jakob Unger Museum, Avenida Hindenburg (near Hotel Florida). Can only be visited together with a Socio, ask at Hotel Florida.edit
Haushaltsmuseum. A museum showcasing artifacts of settlement, and telling the local history. Of particular interest is the section on the Chaco war. The tourist office also runs from here, and they can bring you to see the agricultural processing facility. edit
The Fernheim co-op supermarket and the stores around it are the main places to buy in town; other stores will be found along the main street, selling a wide variety of goods, from second hand clothes to electronics.
Why not send post cards from the post office; a Filadelfia stamped card will have probably one of the most unlikely frank-marks anyone will ever receive from you.
Hotel Florida, Avenida Hindenburg 165-S (Unmissable, right across from the museum and park), ☎ +595 (0491) 432 151, . checkout: 13:00. It might be the nicest spot in town; the reception staff are not very friendly and helpful. The pool is a big bonus though. Also has a decent restaurant (good pizzas).250,000 for a nice twin with air-con, fridge and tv, 100,000 for a very basic room for two with shared bathroom. Dormrooms ad advertised in Lonely Planet are no longer available.. edit
Hotel Golondrina (formerly Hotel Safari), Industrial 149-E (One street across from Chaco Boreal, where the NASA bus office is), ☎ +595 (0491) 32 218. Fairly average place, clean but nothing special. Rooms 135,000 basic twin, 170,000 with air-con and tv.edit
Hotel Las Delphines, Calle Unruh (On the right, white and blue building). Chaotic, dirty, and cheap option, mostly in use by local workers without a house. 35,000 per person regardless of room type; better double or twin rooms with air-con and tv for 120,000. Cheap restaurant in the front.edit
Buses to Asuncion leave at 13:00 and 14:30 daily. Also an overnight bus is possible. 90,000 Gs. Buses tend to be a little old, but usually have air-con.
Bolivia: Catch the 8.30pm bus from the NASA office to Mariscal Estigarriba (1 hour), ask the driver to drop you off at immigration. You will then have to wait several hours for the bus to Bolivia, it is adviseable to wait at the immigration office rather than the bus station due to safety concerns. The bus to Bolivia arrives at 3am when the immigration officer will wake up and issue your exit stamp. You can pre-purchase your bus ticket at Stel Turismo, on the main road in Filadelfia, or buy it in Mariscal. Ask at the petrol station next to the custom. NOTE: Once you have boarded the bus, you will travel for approx 7 hours before you arrive at Bolivian immigration. 300,000 to either Villamontes, or Santa Cruz (They will ask you to pay for the entire journey from Asuncion to Santa Cruz but you can bargain to around 200,000-250,000 in Mariscal).
