Martello Tower in Seaford is a Grade II-listed circular fortress overlooking the East Sussex coastline. Built around 1810 to defend against Napoleonic invasion, this brick structure stands roughly 10 meters tall with distinctive battered walls designed to deflect cannon fire. The tower, measuring 13 meters in diameter on three levels, is the most westerly in a chain of 103 such towers constructed around England's southeastern coast. Today, it is operated as a museum by the Seaford Museum and Heritage Society, allowing visitors to explore its 19th-century gun barrel and authentic defensive features, offering insight into coastal military heritage during the Napoleonic era.
