The Oxo Tower now a top class London restaurant with superb views across the River Thames of the city of London. Built on an earlier-twentieth-centuary electric power station and rebuilt in 1920 with its art nouveau design by the Oxo meat and gravy consortium owned by the Liebig meat company. Unable at the time to have outside advertising on such a high tower the inclusion of the clever window design in the Oxo letters was allowed, whereby at night the red background light illuminates the Oxo sign to the London skyline as our picture insert shows.
