The Pleasant–High Historic District encompasses the earliest area of non-agricultural residential development in Methuen, Massachusetts.

Its primary industrial facility consisted of a gristmill and cotton mill, located at the falls of the Spicket River in what is now the town center.

The construction in 1806 of the Turnpike (now Broadway) led to development of a housing district to its east, on a rise overlooking the area where the falls and mills were located.

After 1855 a number of Second Empire houses were built in the area, and scattered exemplars of other 19th century architectural styles followed.

The principal public space in the district is the site of the American Civil War memorial, located in the triangular area where Pleasant and Charles Streets meet.
