is the name given to the line of cliffs on the southern side of Lithgow between Browns Gap and South Bowenfels. Possibly named by Governor Macquarie during his official tour over the Blue Mountains to Bathurst in April 1815 as it reminded him of when he was stationed in Hassan, India; the mountains there were called the Walls of Hassan. Survey Plans, dated 1832 show land ownership near Hassans Walls. Ref: Sydney Gazette and NSW Advertiser, 23rd August 1832, p. 1.
