But those settlers forfeited their grant by failure to comply with the requirements of the charter, so the territory was re-granted to Dartmouth College on January 19, 1770.

After the Revolutionary War, however, the first grantees successfully claimed that their forfeiture was illegal, so the college had to abandon its title and lose what it had expended in making the settlements.

It was changed by legislative actions over the years: The Lisbon Area Historical Society promotes the public's interest in and appreciation for the towns of Lisbon, Landaff and Lyman, and maintains the collection, preservation and cataloging of materials which establish or illustrate the history of the three towns, their indigenous history and heritage, their exploration, settlement and development, as well as their cultural and artistic heritage.

[1] The highest point in Landaff is the summit of Moody Ledge in the south-central part of town, at 2,326 feet (709 m) above sea level.

Natural features of Landaff include many viewsheds, mountain summits, wetlands, undeveloped woodland and farm land.

Black bear, moose, white-tail deer, beaver, eastern turkey, and coyote are among the animals living in the thousands of open acres, as well as ruffed grouse and other upland birds.

Outdoor recreational opportunities abound for hunting, fishing, cross-country skiing, snowshoeing, hiking, nature observation and snowmobiling.
