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.
