Lendava-Lendva Gallery and Museum was established in Lendava Castle in 1972 by the Cultural Community of Lendava. From 1978 it was placed under the Institute for the Culture of the Municipality of Lendava, but it became an independent institution in 1996.

The Oloris exhibition occupies the first floor of Lendava Castle and presents the Bronze Age settlement of Oloris near Dolnji Lakoš. It is divided into two main sections: the first section introduces the visitor to the discovery of the settlement and how it was researched, and presents the results of the research. The second section displays material from the interiors of the Oloris dwellings, from the courtyard and fringes of the settlement. The exhibition is further enhanced by a reconstructed Oloris house with a hearth and loom, and a courtyard with oven, well, fence and fields, including stone farming tools.

The György Zala Memorial Room is dedicated to György Zala (), one of Hungary's most eminent neo-Baroque sculptors of the 19th century, who was born in Lendava. György was an excellent portraitist and the author of the monumental sculptures of kings and emperors at Hósök tere (Heroes' Square) in Budapest.

The collection of the Lendava-Lendva International Artists Colony exhibits work by local and European artists who have participated since 1972 in Lendava-Lendva International Artists Colonies.
