Perhaps even before Glasgow city was founded, this medieval spring has been quietly gurgling its way through history. The well is situated in an unlikely spot in Scotland’s largest city. At the end of the appropriately named Ladywell Street, the well’s small niche is carved into the western wall of the Glasglow Necropolis and Tennent’s Brewery, home to the UK’s largest beer attraction.

There used to be 16 of these watery founts across the city in 1736, but few have survived into the present. The Lady Well is dedicated to the Virgin Mary and visitors will often drop coins in the well as offerings. The well initially drew water from Merchant’s Park, which would have been outside the city’s walls during the Middle Ages. Roman soldiers perhaps even refreshed themselves at the well during the construction of the Antonine Wall.

Lady Well underwent several reconstructions before it was finally capped towards the beginning of the 20th-century—most notably by the Merchants House, a local chapter of guilds that perform charitable works, in 1836 and again in 1874. Its neighbor, Tennent’s Brewery, had the well refurbished in 1983.
