Located in the historic interiors of Krosno's former Bishop's Palace, this large museum showcases centuries of cultural heritage and artefacts. The museum prides itself on its large collection of lamps and other objects related to the history of lighting from 1860-1920, when the oil industry generated much wealth for the region, following local hero Ignacy Łukasiewicz's invention of the kerosene lamp. Richly decorated in a wide variety of artistic styles, the museum's collection of such lamps is the largest in Europe. As this is Krosno, the museum also harbours a large collection of glassware, including the first functional sets ever produced locally in the 'City of Glass.' Other permanent exhibits also cover the history of the town, with particular emphasis on the region's prehistory and archaeological excavations carried out on Krosno's market square and in nearby Trzcinica, and the works of renowned local painters Seweryn Bieszczad and Stanisław Bergman are well-represented in the museum's Art Gallery. Renovations taking place in 2025 aim to further expand and modernise the museum, with rumours of a permanent exhibit on the Art and Arms of Japan in the future.

In addition to tours of the museum's own extensive exhibits, staff can help organise tours of Krosno's historical monuments in Polish and English. The museum also hosts various events and concerts throughout the year.

Approximate visiting time: 2hrs.
