One of many historic Cape Cod lighthouses. This is a fine spot to view the well-known Breakthrough in North Beach.
Chatham Lighthouse, known as Twin Lights prior to 1923, is a lighthouse in Chatham, Massachusetts, near the "elbow" of Cape Cod. The original station, close to the shore, was built in 1808 with two wooden towers that were replaced in 1841. In 1877, two new towers, made of cast iron rings, replaced those. One of the towers was moved to the Eastham area and became Nauset Light in 1923.
Today, the former keeper's house is an active U.S. Coast Guard station, and on-duty personnel living quarters. Search and Rescue, maritime law enforcement, and Homeland Security missions are carried out here.
Chatham Light is available to tour on Wednesdays, 1 to 4 PM, May through September.
