Fenwick Island — A 1751 Colonial Survey Stone, an 1858 Lighthouse, and a 1953 Vote Against High-Rises

A Boundary Dispute, a Beacon, and a Vote Against High-Rises

Fenwick Island's story starts long before it was a town, with a disagreement over a line on a map. English colonial land grants to Maryland's Calvert family and Delaware's Penn family overlapped, and the resulting Transpeninsular Line survey, run between 1750 and 1751 by John Watson and William Parsons for Pennsylvania and Delaware and by John Emory and Thomas Jones for Maryland, was drawn specifically to settle it. That line runs east-west across the entire Delmarva Peninsula, and its eastern terminus sits right here, at Fenwick Island. A stone marker placed on April 26, 1751 carries the Calvert coat of arms on its Maryland-facing side and details from William Penn's coat of arms on its Delaware-facing side; it was formally ratified by King George III in 1769. That is more than a decade before Charles Mason and Jeremiah Dixon began the survey that would make their names famous in 1763 — the Transpeninsular Line and the later Mason-Dixon Line actually intersect at a single point, forming Delaware's southwestern corner. The stone has stood on what is now the lighthouse grounds for more than 250 years, a genuinely different founding story than any other Delaware beach town's church-retreat or planned-subdivision origins already covered on this site.

The lighthouse that now shares the marker's grounds has its own dated, documented history. The Fenwick Island Lighthouse was completed in 1858, stands 87 feet tall, and is the only brick, conical-type lighthouse ever built in Delaware, according to the Delaware Division of Historical and Cultural Affairs. It was built to help mariners steer clear of the treacherous Fenwick Shoals, six miles off the coast. A French-made third-order Fresnel lens was installed, and the light first shone on August 1, 1859. It operated for roughly 120 years before the U.S. Coast Guard decommissioned it on December 13, 1978. Grassroots advocacy convinced the State of Delaware to acquire the property in 1981, and the lighthouse was re-lit in 1982 as an unofficial, private aid to navigation. It has been listed on the National Register of Historic Places since 1979 — a genuinely deep, multi-century functional and preservation history unlike anything documented at Rehoboth Beach, Dewey Beach, Bethany Beach, or South Bethany.

Human settlement here goes back further still. In 1614, Dutch explorer Cornelius Jacobsen May mapped this stretch of coast, referring to the area as "Hindlopen" or "False Cape." The British took control during the Second Anglo-Dutch War in 1665; the Dutch briefly retook Delaware in 1673-1674 before the British regained permanent control. The town's own name comes from Thomas Fenwick, an English planter who settled in Maryland and owned the surrounding land around 1700 — a different colonial namesake story than any prior Delaware market's founding figure. In the late 1700s, a salt-collection industry operated here, with product shipped north to Philadelphia and beyond. And on October 3, 1932, a dated "Prohibition Shootout" occurred, with the Coast Guard and State Police confronting rum-runners attempting to land roughly 200 cases of alcohol valued at approximately $30,000.

The town itself did not become a legal municipality until 1953, and it did so for an explicit, documented reason. Before then, this was unincorporated land between South Bethany and Ocean City, Maryland. The Delaware General Assembly incorporated Fenwick Island in July 1953 specifically to prevent the kind of high-rise development already reshaping neighboring Ocean City, Maryland from spreading north across the old colonial boundary into Delaware. That is a genuinely explicit zoning motive, plainly stated rather than inferred, and it stands in contrast to the organic-growth, planned-subdivision, and religious-retreat origin stories already documented at the other four Delaware markets on this site.

Geographically, Fenwick Island is a barrier spit, not a barrier island, per Wikipedia's own classification — a distinction from South Bethany's barrier-island geography just to the north. The town totals just 0.49 square miles, 0.33 of that land and 0.15 water, sitting at an elevation of 7 feet, with a man-made canal connecting White Creek to Little Assawoman Bay. Fenwick Island is also jointly branded, along with Bethany Beach and South Bethany, as one of "The Quiet Resorts" by the Bethany-Fenwick Area Chamber of Commerce, though that shared branding is not this town's primary distinguishing story — the boundary marker and the lighthouse are.

Population figures here need honest disclosure rather than a single confident number. The 1960 census counted just 48 residents; by the 2020 census, that figure had grown to 343 residents, though some sources cite 355 — this page treats 343 as the primary Census Bureau figure while flagging that minor variance rather than asserting one number as absolute. The 2000 census recorded 666 housing units. As with every Delaware beach town on this site, there is no state sales tax — a structural fact that applies regardless of which Quiet Resorts-area town a buyer is considering.

On current figures, the honest approach is to hedge rather than guess. No current (2026) median home price, active-listing count, or specific current rental rate for Fenwick Island is confirmed here. No current Sussex County or Fenwick Island-specific property tax rate or assessment figure is stated here; direct those questions to Sussex County government and the Town of Fenwick Island's own finance office. No current FEMA flood-zone designation for any specific parcel is confirmed here. No Fenwick Island-specific damage record from the March 1962 Ash Wednesday Storm was found this research pass, and no dated 2025-2026 storm damage, erosion event, or beach-replenishment project specific to Fenwick Island is stated here as fact. The lighthouse's current visiting hours and admission details are also not confirmed here — only its history, NRHP status, and 1982 re-lighting are.
