Magnesia Well. The Magnesia Well (number 54 on the official list) was identified by Dr. Short in his 1652 book "The Yorkshire Spaw". Recommended as a powerful diuretic, the Magnesia Well contains a mild sulphur water, which was once highly popular, requiring the neighbouring Pump Room to be built in 1858, succeeded in 1895 by the New Magnesia Pump Room, now the Cafe. The water was analysed in 1865 by the celebrated chemist Dr. Sheridan Muspratt. this Well Head was restored in 1999 by the Harrogate Civic Society, the cost having been donated in loving memory of Kit Kelly, by his mother, Irene, and brother, David.
