This is the Annisquam Lighthouse in Rockport, Massachusetts. You can view this lighthouse from the shore. From Route 127 in Gloucestor, turn onto Lane Rd. Take a left onto Elizabeth Road followed by another left onto Wigwam Road and a right onto Lighthouse Road. There is a small parking lot and a set of stairs down to the beach where you can view the lighthouse. The lightkeeper's house is private property, so be sure you don't disturb the residents.
