In the village of Siary near Gorlice, oil was extracted as early as the 17^th century. However, the official discovery date is 1852, when Prince Stanisław Jabłonowski established the first mine in the world for this precious fuel. The first shafts were dug using only human muscle and took place between 1852 and 1854. Oil from Siary found its way to the famous Ignacy Łukasiewicz, who conducted experiments with it. Initially, the unprocessed oil was used as a lubricant for horse cartwheels and hinges. The crude oil that floated to the surface on its own was also used as a preservative for wood. Today, the deposit is exhausted, and most old wells have collapsed. However, persistent explorers may find places where oil still spontaneously floats to the surface. Siary is worth visiting not only because of the oil mine, and there are many more attractions, such as the palace of Władysław Długosz, a Polish oil tycoon. Originally, in place of the palace complex, there was the wooden manor house of the Dembowski family, dating to the 14^th century. The new residence was built between 1900-1908 in Viennese Art Nouveau style. In 1928, the building burned down but was rebuilt in an unchanged form. The estate remained the property of the Długosz family until 1945, when it was taken over by the Germans during World War II and housed a hospital, among other things. In the post-war years, the palace gradually deteriorated, though it housed the State Stud Farm (1950-1994) for many years. Grzegorz Schabiński is the current owner of the palace complex, which includes a restaurant and a hotel.
