The Mechanicsville Historic District encompasses a cluster of residential properties that are all that remain of one of the early industrial areas of Grafton, Vermont.

[1] The area that is now Grafton was first chartered in 1754, but only began to see permanent settlement in the late 1770s, in the town's Middletown section.

Three of its lumber mills (none of which stand anymore) survived into the 20th century, supporting the local economy until the last one closed in the 1960s.

The two non-contributing properties in the district are a modest 2000s Colonial Revival house, and a 19th-century blacksmith's shop that has been moved and converted into a residence.

A metal guardrail now stands in its place, just west of the Howland Mill Bridge.
