The Vihorlat Museum is housed in a 17th-century Renaissance mansion. The manor house was built on the site of a medieval water castle. Today, it is a national cultural monument and a rare historical landmark of the city center. In the 19th century, a park was built around the mansion, which now houses an exhibition of folk architecture.

The Museum started its activities in 1960 and since 2002 it has been administered by the Prešov Self-Governing Region. At present, more than a hundred thousand pieces of collection items are concentrated in the museum's collections. Among the most valuable are the findings of Celtic coins, a mass finding of 17th century coins, unique antique weapons and armor, or Baroque icons.

The museum has four permanent exhibitions:

• Art-historical exposition - offers a view of the nobility's housing culture from the Renaissance to the 20th century.

• Natural science exposition - points to the state of the surrounding nature and thus indirectly to the state of our environment.

• Exposition of sacred art with the Chapel of Our Lady - it presents sacred works of art mostly from the 18th and 19th centuries.

• Exposition of folk architecture and housing - presents the most typical buildings of folk architecture and one sacral building - the wooden church of St. Archangel Michael.

Since 1989, the Museum has also included the Orest Dubay Gallery Hall, which organizes exhibitions of domestic and foreign authors, focusing primarily on information on the life and work of artists from the region. In addition to the permanent exhibitions, the museum prepares a wide range of exhibitions and events for its visitors every year.
