Polskie Towarzystwo Turystyczno-Krajoznawcze, PTTK (Polish Tourist and Sightseeing Society) is a Polish non-governmental tourist organization with 312 branches across the country. The PTTK is one of the oldest tourist societies in Europe. Its origins stretch back to the foreign Partitions of Poland. In August 1873 a group of tourism enthusiasts including painter and photographer Walery Eljasz Radzikowski from Kraków and physician Tytus Chałubiński founded the Polish cultural Tatra Society (Polskie Towarzystwo Tatrzańskie, originally the "Galician" Tatra Society for the Austrian censorship). A parallel Polish Sightseeing Society (Polskie Towarzystwo Krajoznawcze) was founded by ethnographer Zygmunt Gloger in 1906. The two organizations merged after World War II in 1950 to form the PTTK.
