The Museum of Folk Architecture in Sanok popularly named the open-air museum is one of the most-often visited tourist attractions in the broadly understood Bieszczady Mountains. It is situated on the right bank of the San River at the foot of Biała Góra in the Sanocko - Turczańskie Mountains range. It covers an area of 38 ha.
It is the first and largest ethnographic museum in Poland in terms of number of collected objects established after World War II. The museum was established in 1958 from the necessity of saving the remains of folk culture of south-eastern Poland that survived after the war. In 1966, the first facilities were opened for visiting for public. The open-air museum is divided thematically with a marked division into buildings of individual ethnic groups such as Lemkos, Boykos and Pogorzans. These are mostly Orthodox churches, residential houses, utility rooms and other facilities. At the beginning of the 1980s, a project to build the so-called "small town", i.e. showing examples of small-town housing from the turn of the 19th and 20th century, reconstructing the Galician market with all its functions. This project was implemented under the name "Galician market". Thanks to the project, we can now admire the look of residential houses, craft workshops, commercial facilities with equipment from a given epoch, partly adapted for tourist purposes thanks to the arrangement of the old post office, hairdresser, pharmacy or heel bar.
