The Andover Historic Preservation site is a useful tool for people looking for information about specific historic buildings or national historic register districts in Andover. It aims to promote appreciation for Andover's heritage as it is expressed in its unique architecture. Andover Historic Preservation is the product of work done by the Andover Preservation Commission, the Andover Center for History & Culture, and Memorial Hall Library.
