Originally called New Durham Gore, the town of Alton was settled by a group from Roxbury, Massachusetts. There were already two towns named Roxbury in New England, so the town was incorporated as Alton in honor of a prominent family from Roxbury. With a population of 5,100, the town's boundary envelopes the five-mile long Alton Bay, southeastern point of Lake Winnipesaukee, and includes the southern side of Wolfeboro Harbor and all of the largest islands in the southeast end of the lake. Alton's 19.3 square miles of inland water area is the highest among the cities and towns in New Hampshire. Alton is approximately 90 miles from Boston.
