These underground passages were 18th century chalk workings. They were forgotten until 1807 then used as an ice-house; in 1863 a later owner put them on show as "Vortigern Caves" complete with bogus legends. They were closed from 2004 but re-opened in 2019 with a newly built centre with a cafe, gift shop and exhibition space.
The Margate Caves are a tourist attraction in Margate. The caves were originally dug as a chalk mine in the area between Margate and Cliftonville. The caves were opened as Victorian seaside attraction in 1863 under the fictional name The Vortigern Caves. Their walls were decorated with gaudy murals. The cave's popularity continued into the 20th century but were closed in 2004.

This is a remarkable place down a dingy back street: a winding underground passageway leading into a chamber, all decorated from floor to ceiling in sea shells. It was stumbled upon during building work in 1835 and its age and builder are unknown. There's been no scientific dating, and there are several dingbat theories, but it looks like the style of 18th- and 19th-century grottoes or follies that adorn stately homes elsewhere. The shells of the design are local, but the background fill of flat winkles is not — this type is common in Southampton.
Modern art gallery opened in 2011, with a small selection of paintings by JMW Turner (1775-1851), who stayed at a boarding house on this spot. But it's mainly rotating exhibitions of modern art and events.
Amusement park with a dozen rides, including the Scenic Railway, a listed wooden coaster. Many rides have age or height restrictions.
Theatre squeezed into an old coach house with offbeat decor, and a bar with an outdoor balcony upstairs
This is a "smock mill" built in 1865, the only survivor of three here. In 1920 it was fitted with a gas engine to enable work to continue on windless days. It fell into disrepair in the 20th century but has been restored.
Exhibition of Hornby model railways, Airfix models and Corgi car models. Hornby Dublo OO gauge electric model railways hold the same romanticised place in British history as pre-British Rail full-sized trains, but they're firmly rooted in the 20th century and their admirers are a dying breed. So this showcase hall and outlet is effectively a museum.
