Cape Cod has more lighthouses than any comparable stretch of the American coast, for the unromantic reason that this peninsula sank an extraordinary number of ships. A sandy hook sticking sixty-five miles into the North Atlantic, with shoals running out from the elbow and a fog season that arrives with the warm air of early summer, is a hazard rather than a landmark, and the towers were an answer to a body count.
What makes them worth a page rather than a paragraph is that they move. This is the only coast in the country where the sensible way to describe a lighthouse includes where it used to stand. In 1923 one of Chatham's two towers was taken apart, shipped twelve miles up the shore and re-erected in Eastham, where it is now painted red and white and stands on packets of crisps. In July 1996 Highland Light in Truro, a 66-foot brick tower weighing something over four hundred tons, was jacked up and rolled 450 feet inland over eighteen days while the town watched. That November Nauset Light was moved 336 feet from a bluff it was about to fall off, and relit the following May. Three small wooden towers that once stood on the Eastham cliff now sit in a clearing in the woods, roughly a thousand feet back from the sea that chased them there.
The Outer Cape retreats on the order of three feet a year on average, and far more when a winter storm settles in. A lighthouse is a fixed structure on a shoreline that refuses to be fixed, and the history of these towers is really the history of that argument.
Practically, the Cape's lights fall into three groups. There are the ones you can climb, which in most seasons means Highland in Truro, Nauset in Eastham and Nobska at Woods Hole, each on its own limited schedule run by volunteers rather than by a park service. There are the ones you can walk up to and photograph but not enter, including Chatham, whose keeper's house is a working Coast Guard station, and the Three Sisters in their wood. And there are the ones that take real effort: Race Point, a two-mile trudge through soft sand or an over-sand permit, and Long Point and Wood End at the tip of the hook, reached by scrambling a mile of granite blocks across the harbour or by taking the shuttle boat.
Almost all of it is free. Grounds are open year-round at most of these sites, the climbs cost a few dollars where they run at all, and the best hour for photographs is the last one of the day at Nauset or the first one at Chatham. What no guide can tell you reliably is which tower is open on the afternoon you turn up, because the schedules are set by volunteer groups and change every season. Check on the day.
