Also called the Cincinnati Memorial Hall, the Ladd-Gilman House is one of the first brick houses in the state of New Hampshire. It was built in 1721 and has been home to several notable individuals in the Gilman family.

First on the list is Col. Nathaniel Gilman, who bought the house in 1747. He was a well known Exeter merchant and father and grandfather to two of the state?s treasurers, Col. Nicholas Gilman and John Taylor Gilman, who also became a state governor. The Ladd-Gilman House was also the birthplace of Nicholas Gilman, Jr., who was one of the US Constitution?s signers and a former senator from New Hampshire.

The house now operates as the American Independence Museum under the Society of the Cincinnati.
