Long Point Light

Long Point Light Station is a historic lighthouse at the northeast tip of Long Point in Provincetown, Massachusetts. As a navigational aid, it marks the southwest edge of the entrance to Provincetown Harbor. The United States Coast Guard Light List describes it simply as a "white square tower". The light it casts is green, occulting every 4 seconds, and, at a focal height of 35.5 feet (10.8 m) above mean sea level, has a visible range of 8 nautical miles (15 km; 9.2 mi). When the weather affords low-visibility, one can hear the station's fog horn – sounding a single blast for two seconds, and repeating every 15 seconds – as it seems to call out for (and answer calls from) its nearly-identical closest neighbor, the Wood End Light.

History

By an act of Congress on May 18, 1826, the United States Government earmarked $2,500 to acquire 4 acres (0.016 km2) at the extreme tip of Long Point, and to establish a lighthouse to guide mariners into the busy fishing port of Provincetown Harbor. In comparing the relative share of the gross domestic product (GDP), or "nominal GDP", that's the equivalent of today's Congress allocating $48 million in 2013 dollars.

Completed in 1827, the original Long Point Light was not a tower structure, but rather consisted of an octagonal lantern centered on the peak of the roof of the wooden keeper's house. Access to the lantern was by a spiral stair from the top floor of the house. That architectural style, common to several of Cape Cod's early 19th century lighthouses, came to be known as the "Cape Cod style" – today, however, "classic" examples of that style can only be found along the Pacific Coast.
