Weeks State Park, Lancaster

The Weeks Estate is a historic country estate on U.S. Route 3 in Lancaster, New Hampshire. Built in 1912 for John Wingate Weeks, atop Prospect Mountain overlooking the Connecticut River, it is one of the state's best preserved early 20th-century country estates. It was given to the state by Weeks' children, and is now Weeks State Park. It features hiking trails, expansive views of the countryside from the stone observation tower, and a small museum in the main estate house. A small portion of property at the mountain summit was listed on the National Register of Historic Places in 1985. ()
