Wilton is a town in Fairfield County, Connecticut, United States. As of the 2020 census, the town population was 18,503. In 2017, it was the sixth-wealthiest town per capita in Connecticut, the wealthiest U.S. state per capita. Officially recognized as a parish in 1726, Wilton today is a residential community with open lands, historic architecture such as the Round House, and many colonial homes. Many residents commute to nearby cities such as Stamford or New York City. Wilton is home to many global corporations such as ASML, Breitling SA, Cannondale Bicycle Corporation, Melissa & Doug, and formerly Deloitte. It is also home to AIG Financial Products, whose collapse played a pivotal role in the financial crisis of 2007–2008. The transformation from a small farming town to a suburban residential community has been carefully controlled by zoning, efforts to preserve the town's colonial landmarks, and the reservation of almost 1,000 acres (4 km) of open space for active and passive recreational use. The Cannondale Historic District, in north-central Wilton, retains its historic character and was listed on the National Register of Historic Places in 1992. History Colonial days The first written records of the areas that are now Wilton date back to 1640, when Roger Ludlow and his friends purchased land from the Indians between the Norwalk and Saugatuck Rivers and "a day's walk into the country." This land was called Norwalk. The first settlers, called the Proprietors, arrived in Norwalk in 1651 and owned 50,000 acres (200 km) in common. On the outskirts of Norwalk's settled area, the Proprietors were allowed private ownership of land in a common planting field, but cattle, sheep, and hogs were grazed in a communal pasture area. The outer limit of this pasture approximates Wilton's present southern boundary. By the end of the 17th century, the Norwalk Proprietors began to sell off the northern lands for settlement. The first non-Indian settlements in what is now Wilton were in the fertile lands of the Norwalk River valley, and on the ridges of Belden Hill, Chestnut Hill, and Ridgefield Road. In order to till the lands, the settlers had to clear the forests and remove hundreds of glacial rocks, which became the stone boundary walls that are treasured today. The families who bought land in Wilton did not have their own church and were required to attend service in Norwalk each Sunday. When demand for Wilton lands
