Eel Pie Island is a small island in the middle of the Thames opposite Twickenham Embankment, accessible only by a footbridge that is private and mostly closed to the public. In the early 1960s, its ballroom hosted what became known as the Eel Pie Island Hotel concerts — a series of R&B and blues nights that helped launch the careers of the Rolling Stones, the Who, and a generation of British rock musicians. The Rolling Stones were the house band for a period.
The island is now residential — about 50 houses, a colony of artists' studios, and a boatyard. The Eel Pie Island Museum, a small private museum on the mainland opposite, celebrates the island's musical heritage and is open on occasional weekends. It is worth knowing about even if you can only see the island from the Twickenham Embankment across the water.
