Upper Arthur Street is the southward continuation of Arthur Street. It was probably named after Hon. Arthur Chichester (1771-88), son of the 1st Marquis of Donegall (Patton 1993, p. 18).
The street was recorded in 1815 simply as part of Arthur Street. In 1845 it was recorded in Corporation minutes under a separate name as Arthur Street Upper and in 1850 as Upper Arthur Street. See Arthur Street for further details of this name.
