Cedar Point Light was constructed in 1896 to mark the southern side of the mouth of the Patuxent River. $25,000 was appropriated for the light. The light was a three-story cottage with a rooftop lantern. The lantern housed a fourth-order lens. A fog bell was placed in an adjacent tower.

Cedar Point Light was only active until 1928. Built on dry land, the surrounding ground was gradually consumed by erosion. Local dredging made the problem worse. By the 1920's, the light was totally surrounded by water. The light was abandoned in 1928 and a light placed on a nearby post.

The light was moved to the old fog bell tower in the 1950's. After a storm destroyed the fog bell tower in 1957, the light was replaced by a bell buoy. The lighthouse, now on property managed by the U.S. Navy, gradually deteriorated to the point of collapse. In 1996, portions of the lighthouse were removed and transferred to the Calvert Maritime Museum. Only ruins remain at the site.
