Kálmán Mikszáth Memorial House, Literary museum in Horpács, Hungary.

The Kálmán Mikszáth Memorial House is a museum housed in a mansion that the Hungarian writer built himself. The rooms display his personal possessions, written documents, and period furnishings from when he lived there.

Mikszáth bought the roughly 400-hold Horpács estate and its Szontagh mansion in November 1904, first visiting at Easter 1905. Finding the old single-storey house cramped, he had a larger building, originally called a castle, erected from the fee for his book Jókai Mór élete és kora; it was finished by summer 1906 to plans by his elder son, ifj. Mikszáth Kálmán. A Mikszáth memorial room opened in 1954, and the expanded memorial museum was inaugurated on 29 May 1960.

The house is named after writer Kálmán Mikszáth, who made this place his home and workspace. Visitors can observe how a successful author from the early 1900s arranged his daily life here.

The museum entrance is not at the main portico: visitors walk around the left side of the building to get in. The building stands in a maintained park, where a full-length statue of Mikszáth seated on a bench faces the museum and a bust of his wife, Mauks Ilona, stands nearby.

The building was paid for with the fee Mikszáth received for his book Jókai Mór élete és kora, a life of Mór Jókai. It was designed by his elder son, ifj. Mikszáth Kálmán, and finished by summer 1906. The family called it the castle, though it was planned larger than what stands today.
