Derby Wharf and Light Station, Salem

Derby Wharf, once owned by the prominent Derby family business, held a special place in Salem's maritime heritage. Stretching nearly half a mile into Salem Harbor, it served as the city's longest wharf during its active years. Along its length, warehouses brimmed with goods from across the globe, showcasing Salem's role as a vital center for trade and commerce.

At the very tip of Derby Wharf, the Derby Wharf Light was erected in 1871 to ensure the safety of vessels navigating the harbor. Its historical significance was duly recognized when it was added to the National Register of Historic Places in 1987. Perched 25 feet above Mean High Water, the lighthouse's red light, visible for four nautical miles, guided countless ships safely to port.

For many years, the Derby Wharf Light housed one of only 17 sixth-order Fresnel lenses in the United States. These intricate lenses, renowned for their precision and effectiveness, enhanced the lighthouse's visibility and allowed mariners to identify it with ease. The light station relied on an oil lamp to shine through this remarkable lens.

In its continuing commitment to both history and safety, Derby Wharf Light has undergone changes over the years. Today, the light is powered by solar energy, a nod to modern technology while preserving its legacy. The light now emits a red flash every six seconds, providing a modern navigational aid to mariners.
