This collection of 17th - 19th century portraits in the chateau in Strážky consists mostly of works from the galleries of the chateau's previous owners (the Horváth-Stansith, Szirmay, Mednyánszky and Czóbel families, as well as the Spiš families of Csáky, Esterházy, etc).

Ladislav Mednyánszky (1852 - 1919) is one of the prominent representatives of Central European painting of the last third of the 19th century and the beginning of the 20th century. The mansion in Strážky is the only place in Slovakia in which a permanent exposition of his work is presented.

A brief historical exposition introduces the history of the mansion and the municipality and the development of the families who owned the mansion. The beginning of the significant Slovak historical library, which is a part of the national cultural heritage, dates back to the last quarter of the 16th century. The library has developed continuously for 400 years and today it has approximately 8,500 books, magazines and maps.

The Slovak National Gallery is gradually building up its outdoor exposition of plastic art, in which the works of the most prominent Slovak artists of the second half of the 20th century are represented in the impressive English park, which sprawls across the landscape bordering the Poprad River.
