Count Siegfried of the [[Ardennes]] (''Sigefroi'' in French; ''Sigfrid'' in Luxembourgish) bought the feudal rights to the territory on which he founded his capital city of [[Luxembourg City|Luxembourg]], his name became connected with the local version of Melusine. This Melusina had essentially the same magic gifts as the ancestress of the Lusignans. The morning after their wedding, she magically created the Castle of Luxembourg on the [[Bock (Luxembourg)|Bock]] rock (the historical center point of Luxembourg City). On her terms of marriage, she too required one day of absolute privacy each week. Eventually Sigfrid was tempted by curiosity and entered her apartment on Saturday, when he saw her in her bath and discovered her to be a mermaid. He cried out in surprise, and Melusina and her bath sank into the earth. Melusine remained trapped in the rock but returns every seven years either as a woman or a serpent, carrying a golden key in her mouth. Anyone brave enough to take the key will free her and win her as his bride. Also every seven years, Melusine adds a stitch to a linen chemise; if she finishes the chemise before she can be freed, all of Luxembourg will be swallowed by the rock.<ref>{{Cite book |last=Casey |first=Robert Joseph |url=https://books.google.com/books?id=KB0BAAAAMAAJ |title=The Land of Haunted Castles |publisher=Century Company |year=1921 |pages=55-58}}</ref> In 1997, Luxembourg issued a postage stamp commemorating her.<ref>[http://www.luxcentral.com/stamps/LuxStamps1997.html#Europa.1997 Luxembourg Stamps: 1997]</ref>
