The Water Tower is a building in Kenilworth, Warwickshire, England. In the mid 20th century it was nicknamed 'Kenilworth Lighthouse', though the name has now fallen out of usage. Made of brick, it is 90-foot (27 m) tall and was built by Joseph Lee and John Lamb a haberdasher from Warwick in the mid-18th century, and for the next 76 years was a windmill used to grind the corn for the townsfolk. With the windmill machinery on top now redundant, the tower was adapted to allow an iron water tank of 26,000 US gallons (98,000 l; 22,000 imp gal) to be added. It was Kenilworth's primary water source until 1939, and was used as an auxiliary source until 1964. From the early water storage period time, the only extant photographs display signs advertising Singers Cycles of nearby Coventry on the tank. By 1960 the Water Tower was out of use, and it was decided to sell it off as a private residence.The conversion work began in 1972 and took two years.
