These aren’t new for 2026, but they remain a firm favourite of the House Keeper on the rare occasions she leaves the estate. We don’t ask what she does on her days off, and she has never volunteered the information (which feels like the safest arrangement for everyone involved).

Hidden London’s tours return throughout the year, offering guided descents into abandoned Tube stations and forgotten tunnels. The sort of places where the air feels older than it should, and the lighting seems to have given up long before you arrived.

Aldwych, Moorgate, Down Street… each tour promises dim lighting, unsettling silence, and the faint suspicion that someone else is down there with you. Someone who didn’t pay for a ticket.
