The city bought the palace in August 1903. During reconstruction of the palace, a series of six unknown tapestries was found folded behind wallpaper, depicting the ancient legend of Hero and Leander, illustrating their tragic love.
The tapestries were woven in the 1630s in the royal weaving workshop at Mortlake near London, run by the Dutch Phillip de Maecht. The designs and tapestries created by Franz Cleyn reflect Flemish and partially Italian painting from the period of Mannerism.
Apart from English tapestries, the grand halls of the Primate's Palace show several smaller exhibitions of paintings from the collections of the City Gallery of Bratislava - a collection of 17th century Dutch and Flemish genre painting and the exhibition of 16th and 17th century Italian painting.
