A historic house museum is a house of historic significance that is preserved as a museum. Historic furnishings may be displayed in a way that reflects their original placement and usage in a home. Historic house museums are held to a variety of standards, including those of the International Council of Museums. Houses are transformed into museums for a number of different reasons. For example, the homes of famous writers are frequently turned into writer's home museums to support literary tourism.
