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.

A statue park was built around the Hrabéczy House. The statues are made of László Holló and Ferenc Medgyesy. Several new artworks will complement the already installed ones.

The tenders of the Holló Heritage strive to keep up the memory of the artist who died three decades ago. The László Holló Circle of Friends tends to this task. They organize a wreathing every year on the birthday of the artist, on 6 March. According to the traditions, the widow of the artist gives the Holló Prize to an artist who greatly deserves it.
