The László Holló Memorial Museum was founded by the caretakers of the heritage of the artist in 1978. The material first exhibited in the Hrabéczy Cottage was moved to Debrecen two decades later. The collection is still maintained by the Déri Museum. Besides the Cottage that is on a territory of one acre, a beautiful park hosts the museum, which does not only include the works of the artist but also the efforts of his brother-in-law, Ernő Hrabéczy as well.
