The Town of Darien has been incorporated in May 1820. Originally part of Stamford, the area was known as Middlesex Parish since 1737, which is reflected on the Town Seal. Today, Darien is mostly a suburban residential community with no industrial enterprises.

Originally part of Stamford, the area we know as Darien became Middlesex Parish in 1737.  It was incorporated as the Town of Darien in 1820.  The first planters, as they were called, took title to the land in 1640, when the New Haven Colony bought from the Indians a tract of wilderness where the Rippowam River met the waters of Long Island Sound.  The Indians in the Stamford area at that time were a generally peaceful tribe of Siwanoys – “the south people” – who lived in small villages of bark-covered wigwams, and who spent their lives fishing, hunting and tending their corn fields.
