Built in 1839, the Arsenal was designed by noted architect James Dakin and is associated with an infamous battle that happened after the Civil War. During the period of Reconstruction several clashes occurred throughout the state between integrated and white supremacist groups. In 1874, the Battle of Liberty Place, wherein the Metropolitan Police of New Orleans were pitted against the Crescent City White League, occurred. The White League prevailed, forcing the Metropolitan Police into the Customhouse and the Cabildo. From the adjacent Arsenal, the Police fought back by shooting cannonballs toward Chartres Street.

Today, the Arsenal offers exhibits and occasional recreational and educational events.

Located on the historic Cos Cob Harbor, home of Connecticut's first art colony, the Society's facilities include the National Historic Landmark Bush-Holley House (c. 1730); the Visitor Center, housed in a former village post office (c. 1805); the Hugh and Claire Vanderbilt Education Center, set in a mid-19th century barn and artists' studio; and the William E. Finch, Jr. Archives.

Bush-Holley House is the centerpiece of Bush-Holley Historic Site on Cos Cob Harbor. A unique dual interpretation provides visitors with two distinct museum experiences that portray the history of the house: the era of the Bushes, a colonial family who lived and farmed on the site from 1790 to 1825, and the Cos Cob art colony period from 1890 to 1920. Eight rooms tell a story of change over time, beginning with the turn of the 20th century and moving backward in time to the Federal era. On the outside the historic buildings, landscape and gardens are restored to c. 1900.

The society offers exhibits, educational programs, research library access, and recreational and educational events; the Bush-Holley Historic Site offers tours and occasional recreational and educational events.

A boomtown founded in 1835, St. Joseph competed with Apalachicola as a trading port on the Gulf Coast of Florida. The original settlement lasted only nine years, but during its short life the city hosted Florida's first State Constitution Convention. The Museum commemorates the work of the 56 territorial delegates who drafted Florida's first constitution in 1838. Following four more constitution conventions, Florida was finally admitted to the Union in 1845 as the 27th state. Visitors can take a self-guided tour through displays and exhibits of 19th-century life in St. Joseph. Life-size, audio-animated mannequins in the replicated convention hall demonstrate the debate and process of drafting a state constitution.
