Stegmoor

Stegmoor was a town in Cornwall. A Voord ship crashed on Stegmoor's beach in the 20th century. UNIT and the Third Doctor were sent to investigate but were unable to find the ship. In 2017, Stegmoor's dam broke, flooding the parts of the town below sea level and uncovering the Voord spaceship. (AUDIO: Beachhead)
