Cheltenham owes it Spa town status to the humble Pigeon. According to tradition, Cheltenham's spa water was discovered in 1716 because local people noticed pigeons pecking at the salty deposits left around a spring in a field on the south of the town.
William Mason, the owner of the field, started to charge for the medicinal water and created the towns first Spa. In 1739 Masons son-in-law, Henry Skillicorne, created a deeper well on the site, installed a pump and built a brick canopy to shelter the drinkers of the water. As the site developed he constructed a Spa building and linked the well to the town with a walk way of trees, later known as Well Walk. The popularity of the Spa grew and the water was bottled and sold in Cities around the country. In 1788 King George and his family visited the Spa and this secured Cheltenhams popularity and its Spa status.
After the regal visit the Spa became known as the Royal Well (now the area occupied by the Ladies College). By the turn of the 1800's the Royal Well was supplying water to about two thousand visitors a year, and this success lead to nearly a dozen other Spas opening in and around Cheltenham by the 1850's. As the century moved on the water tasting and bathing continued but in the early 1900's the Spas began to close and the buildings were used for other businesses. Today you can still try the spa water at the Town Hall and the Pitville Pump Room, having tried it myself I can tell you it is salty and not very pleasant!
Without the pigeon, the bird that some people call 'rats with wings', who knows how different Cheltenham's history might have been.
