The town has a picturesque common, presided over by a Federal-style church and bordered by antique homes.

With a pretty New England common set atop an elevated tongue of land, the village has been noted since the 19th century for its charm; while in "... beauties of landscape, Wentworth has a more than ordinary share.

With abundant water power from the Baker River, Wentworth developed into a lumber-producing town with nine sawmills.

It raced 3 miles (5 km) down the steep, rocky channel, then undermined and washed away Wentworth's riverside mills, houses, barns, sheds and roads.

The highest point in Wentworth is Carr Mountain in the northeast corner of town, at 3,453 feet (1,052 m) above sea level.

Wentworth uses a town meeting form of government administered by a three-member Board of Selectmen serving staggered three-year terms, with one seat elected each year.

In the New Hampshire General Court, Wentworth is in the Grafton 11th and 16th House Districts, represented by Beth Folsom (R) and Jeffrey Greeson (R), respectively.
