'Bayswater' recalls Bayard's Watering, recorded in 1380.
It was a watering place on the River Westbourne, where the stream crossed today's Bayswater Road; the river itself was long known as the Bayswater rivulet. In Middle English the name meant either a watering place for horses or one belonging to the Bayard family. The station opened in 1868 as Bayswater and for some decades added Queen's Road to its name.
