A lively town on the outskirts of London, St. Albans is known for its historic cathedral, and it also holds reminders of a long history. From AD 50 to 440, the town then known as Verulamium was one of the largest communities in Roman Britain. You can explore this past in the Verulamium Museum and splendid Roman sites around the area. For activities more focused on the present, every Wednesday and Saturday the Market Place on St. Peter's Street bustles with traders from all over England, selling everything from fish and farm produce to clothing and CDs. A 20-minute drive away from St. Albans is Warner Bros. Harry Potter Studio Tour, which has sets and props from the successful films.
