Castlenova
The notorious 18th-century womanizing dandy whose chief means of impressing the ladies was to give them guided tours of his huge and fancy stone fortress.
Helen of Troy may indeed have had a "face that launched a thousand ships", but Castlenova's personal charm and the grandeur of his palace is known to have attracted nigh-onto-a-thousand Helen-faced damsels, so I dunno which legendary subject is more impressive overall.
