- Situated on the River Anton, a tributary of the Test, the historic market town of Andover boasts two museums in the same building. Andover Museum, telling the story of the town and surrounding area, opened in 1981, and it was joined in 1986 by the Museum of the Iron Age, which tells the story of nearby Danebury hillfort. Grade II listed, the museum building started life as a Georgian townhouse in the mid 18th century. Evidence of this can be seen in the fine staircase, wooden panelling and decorative fireplaces. In the 1840s, the building was purchased by local philanthropist Martha Gale who gifted it to Andover Grammar School. The brick extension that houses the Museum of the Iron Age was added in the 1880s.
