One of the first of thousands of patriots who would die in the war for American independence, Hale is Connecticut's official State Hero. He was born and spent most of the short life he courageously sacrificed on this 400-acre farm. Hale, a Yale-educated schoolteacher, was commissioned a first lieutenant in the Continental Army in 1775. A year later he volunteered to go behind British lines on Long Island to gather military intelligence desperately needed by General George Washington. The British captured Hale and, when they discovered he was a spy, executed him. He was 21. In 1776, Hale's father rebuilt the Homestead, which has changed little since. Its furnishings include collections amassed by pioneer Connecticut antiquarian George Dudley Seymour and several Hale family possessions.

The homestead offers exhibits and tours.

John Langdon rose from modest origins to become a merchant, shipbuilder, Revolutionary leader, signer of the United States Constitution, and three-term governor of New Hampshire. The house he built for his family in 1784 expresses his status as Portsmouth's leading citizen and was praised by George Washington, who visited there in 1789. Its reception rooms are ornamented by elaborate wood carving in the rococo style. After Langdon's death in 1819, the house was occupied by other leading families. At the end of the 19th century, Langdon descendants purchased the house and restored it to its 18th-century state, adding on a substantial wing designed by McKim, Mead, and White to house modern conveniences.

The house offers tours.

This building was the capitol for only four days in 1855, but many believe that the actions of the legislature that met here led directly to the Civil War. Governor Andrew Reeder picked this location, away from the proslavery influence of Missouri, where the legislature would choose a permanent seat of government, create a constitution, and decide if Kansas would be a free or slave state. Instead the legislature kicked out the antislavery members and passed a bill to move the government to Shawnee Mission near the Missouri border. Inside this native stone building visitors will learn the stories of the antislavery and proslavery people of territorial Kansas, set alongside the beauty of the Kaw River Nature Trail.

The site offers exhibits, tours, and educational and recreational events.
