Things to Do in Fenwick Island

The Fenwick Island Lighthouse: A Real 1858 Landmark

The Fenwick Island Lighthouse was completed in 1858 and stands 87 feet tall, and according to Delaware's own Division of Historical and Cultural Affairs, it is the only brick, conical-type lighthouse ever built in the state. It went up specifically to help mariners avoid the Fenwick Shoals, a hazard sitting six miles offshore, and it was fitted with a French-made third-order Fresnel lens. The light was switched on for the first time on August 1, 1859.

It then operated continuously for roughly 120 years before the U.S. Coast Guard decommissioned it on December 13, 1978. Grassroots advocacy led 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 -- a role it has held ever since. It has been listed on the National Register of Historic Places since 1979, recognition that predates the state's own purchase of the site.

We did not confirm current visiting hours, tour availability, or admission details for the lighthouse this research pass, and none are invented here. Check current visiting information directly before planning to go inside or tour the grounds on a specific schedule.

The Transpeninsular Line Marker: Older Than the Mason-Dixon Line

On the lighthouse grounds sits a stone marker placed on April 26, 1751, at the eastern terminus of the Transpeninsular Line -- the boundary survey run across the Delmarva Peninsula in 1750 and 1751 to settle a real territorial dispute between colonial land grants held by Maryland's Calvert family and Delaware's Penn family. The marker bears both families' coats of arms, and the line itself was formally ratified by King George III in 1769.

That makes this marker older than the far more famous Mason-Dixon Line, whose survey did not begin until 1763. The two lines actually intersect at a single point, where the Mason-Dixon Line's southern terminus meets the Transpeninsular Line at roughly its midpoint, forming Delaware's southwestern corner. More than 250 years later, the stone is still there, on the same grounds as the lighthouse, as a genuinely visitable piece of colonial-era history rather than a plaque describing something long since removed.

Beach and Canal, the Rest of a Day Here

Fenwick Island sits on a barrier spit rather than a barrier island, with direct Atlantic beach access as the other half of what brings people here. A man-made canal also connects White Creek to Little Assawoman Bay, running through town and giving a calmer-water option for anyone who wants a break from surf and open ocean, whether that means paddling, fishing from a dock, or just a quieter shoreline to walk.

Fenwick Island is also one of the three towns, alongside Bethany Beach and South Bethany, jointly branded 'The Quiet Resorts' by the Bethany-Fenwick Area Chamber of Commerce, which sets expectations honestly: this is a beach-and-history day, not a boardwalk-and-nightlife one.

What We Will Not Invent

This page is built around real, confirmed facts: the 1858 lighthouse's construction, its 1859 first lighting, its 1978 decommissioning, its 1981 state acquisition and 1982 re-lighting, its 1979 National Register listing, and the 1751 Transpeninsular Line marker on its grounds, ratified in 1769 and predating the Mason-Dixon Line. It does not name specific current restaurants, shops, or annual events, because none were confirmed this research pass, and it does not state current lighthouse visiting hours or tour details for the same reason. Confirm current visiting information, listings, and schedules directly with the Town of Fenwick Island and the Bethany-Fenwick Area Chamber of Commerce before planning a visit.
