Roald Dahl Plass sits at the heart of Cardiff Bay, a broad open piazza flanked by eighteen concrete towers and named after the author who was born a short walk away in 1916. It's an oddly fitting tribute. Dahl's father was a Cardiff shipping broker, and the Plass occupies what was once the Bute West Dock, opened in 1839 at the height of the coal trade that made Cardiff one of the world's busiest ports.

The stainless steel Water Tower near its centre, designed by William Pye, occasionally shimmers with cascading water. Most visitors, though, know it as the Torchwood Tower, the fictional entrance to the underground Hub in the BBC series. The connection runs deep: Cardiff Bay was the show's primary backdrop, and Ianto's Shrine, a steadily growing fan memorial, still draws pilgrims nearby.

VoiceMap's Cardiff Bay tours trace the Plass through three overlapping worlds: the industrial dock history buried beneath it, the Roald Dahl connection woven into the waterfront, and the Torchwood filming locations that turned the bay into a TV landscape.
