Guilford was started with a contract. In the spring of 1639, on shipboard somewhere between Surrey and the New England coast, a Puritan minister named Henry Whitfield gathered the twenty-five men who had sailed with him and asked them to sign a covenant of association: how they would govern themselves, divide the land, build the town. They signed it before they landed. By that September, Whitfield and his planters had stepped ashore on the Long Island Sound coast just east of New Haven, purchased the country from the Menunkatuck people of the Quinnipiac world, laid out a twelve-acre green that is still one of the largest in New England, and begun building. The stone house Whitfield put up that same year — pulled together from the local fieldstone that the glaciers had left lying around for him to use — has stood ever since. It is the oldest stone house in New England, the oldest house in Connecticut, and the first house in the state to become a public museum, opened in 1899. The Hyland House went up around 1660, a saltbox of the First Period that is still on Boston Street today. The Thomas Griswold House dates to 1774 on the road to Madison. The Medad Stone Tavern was built in 1803 just north of the green. Guilford incorporated as a town in 1718. In 1802 a stone tower with an oil lamp went up on Faulkner's Island, three miles offshore in the Sound — Faulkner's Light, the second-oldest active lighthouse in Connecticut. Later in the nineteenth century the pink-grey granite quarries at Stony Creek, on the Guilford-Branford line, began shipping stone to building sites across the country: the pedestal of the Statue of Liberty, dedicated in 1886, was cut from Stony Creek granite, and so was the base of Grant's Tomb. Through all of it the green has stayed the center of town — twelve acres of grass, a Greek Revival meeting house from 1830 along one edge, and the white houses of the planters' descendants set around it in the same square those twenty-five men sketched on the deck of a ship in 1639. On the green since 1639, in the stone house since 1639, and on the Sound since long before that.
What's with the Green Stones of Guilford? Along stretches of Guilford shoreline you can spot pebbles with an unexpected green cast, sea-tumbled pieces that flash when the light hits and make beach walkers slow down. Green Stones is the nickname for those polished fragments that look like tiny gems against sand and gray rock. A quick trick is the rinse test: dip one in saltwater and the color deepens for a moment, as wet surfaces change the way light reflects. That little reveal feels like a secret even though it is just optics. With glacial deposits feeding the coast and waves sorting by shape and density, Guilford ends up with pockets of green that read like scattered notes from deeper geology, bright and brief in your palm — and now and then, on the same stretch, a flake of pink-grey Stony Creek granite that escaped the quarry and made it to the tide line.
Guilford was settled in September 1639 by Reverend Henry Whitfield and a group of English Puritans from Surrey and Kent. The Menunkatuck people of the Quinnipiac world had farmed and fished the shoreline for generations before. Colonial settlers built farms and homes around the twelve-acre town green, still central today. Its founding identity reflects resilience, cooperation, and heritage. Guilford endured storms and hardship but thrived through community strength. Its story highlights Connecticut's duality: Indigenous continuity and colonial determination. The town's origins demonstrate a shoreline community rooted in pride, endurance, and tradition, creating a heritage that remains visible in its historic homes, churches, and community spirit across centuries.

Guilford grew as an agricultural hub, producing crops, timber, and livestock. Shipbuilding and quarrying expanded its economy in the eighteenth and nineteenth centuries — by the 1880s the Stony Creek granite quarries along the Guilford-Branford line were shipping pink-grey stone to major construction projects across the country, including the 1886 pedestal of the Statue of Liberty and the base of Grant's Tomb in New York. Faulkner's Light went up on the island three miles offshore in 1802. By the twentieth century, suburban growth reshaped Guilford, with neighborhoods and schools expanding in the 1950s and 1960s. The town maintained its historic character, preserving colonial homes and the town green. Its timeline reflects Connecticut's dual story: colonial heritage adapting to suburban growth. Guilford's mid-century decades highlighted pride in tradition while embracing suburban expansion, making it a community that balanced continuity and adaptation while maintaining resilience across centuries.
Guilford's lore includes myths of pirate treasure hidden offshore, Revolutionary War skirmishes, and stories of storms testing resilience. Families recall parades, clambakes, and fairs on the green in the 1950s, the Guilford Fair every late September since 1859, and the long-running family orchards on the inland slopes — Bishop's Orchards just north of the green has run continuously since 1871, five generations and counting, and the peach and apple seasons mark the late-summer rhythm of the town. Residents remembered the quarrying era when Guilford-shipped granite was rising in New York Harbor, and the suburban celebrations of the mid-twentieth century. Myths and memories together highlight Guilford's layered identity: colonial farming hub, maritime community, granite-shipping inland town, and modern shoreline village.
Our Guilford retro logo uses Connecticut's clam shell motif, the brand-wide shellfish emblem of every Merlin Classics CT shoreline town, symbolizing shoreline abundance and resilience. The clam reflects heritage, while "1636" ties the design to the Connecticut Colony's founding era — Guilford itself was settled three years later in 1639, but the colony-wide "1636" date is the brand-pattern anchor across our Connecticut towns. Its black-and-white styling is retro, resembling oyster crate labels and coastal signage. The motif bridges Guilford's dual identity: colonial farming and shoreline town and modern shoreline community. On merchandise it conveys authenticity, resilience, and pride, retro in tone. The clam shell emblem honors Guilford's layered story, making it a vintage symbol of Connecticut shoreline tradition.
Today Guilford is celebrated for its 1639 Whitfield House, its twelve-acre green, its First-Period colonial homes, its 1802 lighthouse on Faulkner's Island, its September fair, and the orchards on the inland slopes. Its story reflects Indigenous continuity, the Twenty-Five Planters and the 1639 Covenant, two centuries of New England town-green tradition, granite that traveled to New York Harbor for the Statue of Liberty pedestal, and modern shoreline life. Our Guilford designs celebrate this layered identity, pairing the clam shell motif with vintage styling. They invite you to explore the Guilford collection and carry forward a reminder of Connecticut's oldest stone house and the green that has been the center of town since 1639.
