Sunderland, commonly known as Sunderland Point, is a small village among the marshes, on a windswept peninsula between the mouth of the River Lune, and Morecambe Bay, in the City of Lancaster district of Lancashire, England. It was used as a port for slave ships and cotton ships but its importance declined as other ports such as Lancaster were opened up. The village is linked to neighbouring Overton 1.5 miles (2.4 km) away by a single-track road crossing a tidal marsh, which is flooded at high tide. Strictly speaking, "Sunderland Point" is the name of the tip of the peninsula on which the village of Sunderland stands, but the name is frequently applied to the village itself.
