Queen Street, London
Queen Street is a street in the City of London which runs between Upper Thames Street at its southern end to Cheapside in the north. The thoroughfares of Queen Street and King Street were newly laid out, cutting across more ancient routes in the City, following the Great Fire of London in 1666; they were the only notable new streets following the fire's destruction of much of the City.
