Slaughter Beach is a town in Sussex County, Delaware, United States, located on the southwest shore of Delaware Bay. The population was 207 at the 2010 census, an increase of 4.5% over the past decade. It is part of the Salisbury, Maryland-Delaware Metropolitan Statistical Area. History Slaughter Beach was founded in 1681 and incorporated in 1931. There are at least three stories of where the town's name came from: The first is that it was named after William Slaughter, a local postmaster in the mid-19th century. The second story claims “the name came from the horseshoe crabs that wash up on shore and die each year. They come near shore to shallow water to lay their eggs and the low tide strands them leaving them to die, thus the "slaughter."" The third story, and the most contested source of the town's name, stems from a local legend which tells of a man named Brabant who, in the mid-18th century, "slaughtered" several indigenous inhabitants by cannon in order to prevent an impending massacre. In 2018, PETA wrote to the mayor and followed up with a press release requesting the town change its name to "Sanctuary Beach" and offered to help pay for new signage if the name was adopted. Mispillion Lighthouse Slaughter Beach was home to the last wooden frame lighthouse in Delaware, the Mispillion Lighthouse. The lighthouse, which overlooked the Mispillion River and Cedar Creek, was established in 1831 with a 65-foot tower. The lighthouse was on the National Register of Historic Places. In 2002 the lighthouse was partially destroyed when it was hit by lightning. The lighthouse was later purchased privately, transported down the bay via barge, and incorporated into a private residence in the town of Lewes. Wildlife Slaughter Beach is also home to the Milford Neck Wildlife Area. Tourists are attracted to this area for birding, as many birds stop over to eat the eggs of horseshoe crabs as they lay their eggs on the beaches. Along with Broadkill, Fowler, Kitts Hummock, Pickering, and Primehook beaches, this area is officially designated as a sanctuary for horseshoe crabs, the state marine animal of Delaware and a "signature species" of the Delaware Bay Estuary. Because Slaughter Beach is such an important area for the continued survival of horseshoe crabs and the migrating birds that depend on their eggs, the town has adopted the horseshoe crab as its official town
