New Hampshire State Register of Historic Places The New Hampshire State Register of Historic Places is a register of historic places by the state of New Hampshire and the New Hampshire Division of Historical Resources. Buildings, districts, sites, landscapes (such as cemeteries, parks or town forests), structures, or objects can be added to the list.
