For 189 years the Butler-McCook House and Garden was home to four generations of a family who participated in, witnessed, and recorded the evolution of Main Street between the American Revolution and the mid-20th century. The house's exterior looks much as it did when it was built in 1782. Behind it is a restored Victorian ornamental garden, originally laid out in 1865. Inside are the original furnishings ranging from Connecticut-crafted colonial furniture to Victorian-era toys and paintings to samurai armor acquired during a trip to Japan. The objects were accumulated over the course of more than 125 years by members of this clan, which included physicians, industrialists, missionaries, artists, globe trotters, and pioneering educators and social reformers. The Main Street History Center's keystone exhibition, "Witnesses on Main Street," uses the Butler and McCook families' words and experiences to chronicle their neighborhood's transformation from a clutch of clapboard dwellings, taverns, and artisans' shops into a modern urban enclave of multistory steel, brick, and stone structures housing major financial, industrial, governmental, and cultural institutions.

The Bellamy-Ferriday House and Garden embodies the dramatically different passions of two individuals. Bethlehem pastor Joseph Bellamy, a renowned leader of the Great Awakening, the emotional religious revival of the 1740s, built the house around 1754. In 1912, New Yorkers Henry and Eliza Ferriday acquired it as a summer residence. Around 1915, Mrs. Ferriday designed a formal garden with historic roses, peonies, lilacs, and other flowers. The Ferridays' daughter, Caroline, restored the house, furnished it with Litchfield County antiques, and maintained the magnificent garden, refining the property as a combination of natural and manmade beauty.

The 1678 Joshua Hempsted House is one of New England's oldest and best documented dwellings. Joshua Hempsted lived here his whole life, filling many roles, including farmer, judge, gravestone carver, shipwright, and father of nine children left motherless by his wife's death in 1716. The Hempsted House survived the 1781 burning of New London by the British, commanded by traitor Benedict Arnold. Later, it may have been a safe house on the secret Underground Railroad which aided fugitive slaves seeking freedom. Adjacent to the Joshua Hempsted House is a rare stone dwelling built in 1759 by his grandson Nathaniel. Both houses' furnishings include original Hempsted family objects.

The houses offer exhibits and tours.

The Avery Point Lightouse, located at the southeastern end of the University of Connecticut's Avery Point campus, was built in 1943 to aid the Coast Guard station at Avery Point. Unfortunately, when the station closed in 1967, the maintenance and upkeep of the lighthouse was neglected. In 1997, the University of Connecticut considered razing the structure. This was prevented thanks to the efforts of the Avery Point Lighthouse Society, which culminated in the relighting of the lighthouse in 2006. The tower is not open to the public.
