The project „Develop a Knowledge and Understanding. Tourist Trail of the Lubomirski Family Nests” was carried out by the District Museum in Stalowa Wola in the frame of the Phare programme financed from the EU funds. The application was accepted in 2004 by the Carpathian Euroregion, which played the role of the institution managing and implementing the Small Project Fund. The project combined the necessity of a wider application of the cultural resources and the touristic attractiveness of the borderlands: Subcarpathian Voivodeship in Poland and Prešov Region in Slovakia around the historic buildings on both sides of the border which belonged to the Lubomirski family in the past. The aim of the project was to strengthen the transborder cooperation between cultural institutions, universities, organizations and local authorities. The products of the project include: a map, brochure, CD, website, tourist trail informational leafl ets published in three languages: Polish, Slovak and English. Also educational packages serving the popularization of the project were drawn up for teachers of history, geography, biology and arts. The project was carried out from February until October 2004. The cost of the project was over EUR 21,000, of which 75% came from the EU funds.
