The planned programme examines the maritime reasoning behind the ring of stone castles used to try to pacify Wales. It asks how the realities of the sea affected castle design, with a proposed account reaching back to Roman times and following the idea forward. A science-fiction comparison asks whether bases are better placed on moons, other large satellites, or asteroids than on a planet's surface. The announcement raises these questions without yet explaining the reasons for those choices.
