Newtownards is overlooked by Scrabo Hill , 2km southwest of town. It was once the site of extensive prehistoric earthworks, which were largely removed during construction of the 41m 1857 Memorial Tower , built in honour of the third Marquess of Londonderry, and visible for miles around. Its interior is falling into disrepair and has been closed to the public, but you can still access the surrounding country park .
The disused sandstone quarries nearby provided material for many famous buildings, including Belfast's Albert Memorial Clock Tower.
