Tibor Gallé (1896-1944), an artist was born and raised in Harta. His paintings were bequeathed to the village by his parents. The first local exhibition "An artist and his homeland" opened in 1976. According to the grantors' will most of the pictures displayed depict Harta and its people. Besides having art historical values, they illustrate local history as well.

The copper engravings and lino cuts inspired by the landscape and village people were exhibited in Budapest and in many corners of the world promoting the achievements of the Hungarian art. In Tibor Gallé Memory room, the pictures that were displayed in different places are now collected and exhibited together.

The collections are continuously expanding thanks to the sustained efforts to guard Harta's traditional values.

The end of WWII made sorrowful changes in the colourful history of the village: 287 German families were deported and 243 families were located in Harta. These people with Hungarian mother tongue came from several villages of the Upper Hungary (Modern Slovakia) region: Alsószeli, Csölösztő, Diószeg, Garamlök, Garammikola, Gútor, Kálna, Kisbalog, Kisfödémes, Kismácséd, Kispeszek, Kisújfalu, Léva, Losonc, Nagybalog, Nagysalló, Nagyfödémes, Nagymácséd, Nagypeszek, Nyírágó, Osgyán, Pádár, Rimaszombat, Somorja, Taksony, Tejfalu. After a hard beginning of their coexistence with the local community, people became reconciled to their common fate, and started to work together successfully establishing the development of the village.
