Royal Pump Room
Built in 1842, the Royal Pump Room is located on top of Europe’s strongest sulphur well and is a stone’s throw from Karl’s warden-controlled flat. Visitors can still sample Harrogate’s infamous spa water there which is renowned for its healing properties and general rancidness.
The water actually ran out in 1998 and was replaced with Sunny Delight. No-one seems to have noticed.
