A town incorporated in 1802, before that it was a parish first recognized in 1726 and was part of Norwalk. Coordinates are for Ridgefield Road near the town center

Geologically, Wilton lies within the Connecticut Valley Terrane of metamorphic rocks. The north central part of town is underlain by members of the Ordovician Harrison Gneiss metadiorite. A small body of ultramafic rock crops out at the southern end of these metaplutons, just north of the town center. A belt of Ordovician Rowe Schist lies to the east of the Harrison Gneiss (along northern US Route 7 and under Honey Hill), Both these rock units are surrounded by Ordovician unnamed felsic orthogneiss, which at the southern end of town is mixed with the Ordovician Trap Falls Formation.
