Elkridge qualifies as the oldest settlement in its present county, when Howard was a part of Anne Arundel County. Its location on the Patapsco River was a key element in its growth. The settlement was founded as a place where planters, who each had a wharf along the river, could bring their tobacco crop to be loaded on English trading ships. Later, Elkridge Landing was built as the seaport dock for the community.
Elkridge has historic churches, including Melville Church on Furnace Avenue. Its original building was the first Methodist church built (1772) and was visited on the circuit rides of Francis Asbury. Saint Augustine Church, on Old Washington Road, was built in 1845 and opened its parochial school in 1870. Elkridge had a rich history of industries, including pig-iron forging, basket weaving, paper, cotton and grist milling, as well as employment from the B&O Railroad.
