The Watchet Harbour Lighthouse is marine navigational aid marking the entrance to a Marina within the historic town of Watchet, in Somerset, England.
The cast iron lighthouse is approximately 22 feet metres in height and has a red hexagonal tower with white lantern, and green lens.
The lighthouse is a harbour navigation mark and does not emmit a flashing light associated with traditional Lighthouses. Instead it displays a fixed green luminaire marking the starboard (right hand side) approach to the marina.
The lighthouse is owned and maintained by Watchet Marina.
Little is known about the lighthouse. It was constructed at the same time as the current east pier in 186o by Hennets of Bridgwater. It has continued to provide navigational service throughout the ports history ever since.
