The renovation cost HUF 8 million and was supported by PHARE funds from the EU, said mayor Csaba Szabó.
The renovation involved replacing the museum's roof and painting inside and outside.
The museum recreates a typical peasant family's home in the first half of the 20th century. It features a "tower bed" with nine layers of pillows, decorative plates, a cradle, kitchen utensils and farm implements.
Hollokö was inscribed on the UNESCO World Heritage List in 1987. The village, which developed mainly during the 17th and 18th centuries, is a living example of rural life before the agricultural revolution of the 20th century.
