Heritage Open Day: The Old Magnesia Well Pump Room is a listed building designed by architect John Stead in 1858 to serve magnesia water to Harrogate Spa visitors. Inside is a working recreation of the pump and an exhibition of the history of Valley Gardens. At the heart of Valley Gardens is a unique geological area called Bogs Field, named after the 36 different mineral water springs that emerged in this area. No other place on earth has such a variety of waters so close together.
In 1841, wellheads were built and Bogs Field was drained. As part of the improvements in 1858, a small pump room was built to serve one of the most popular drinking waters, the Magnesia Water.
