Mahee Castle is a small ruined tower house near Nendrum Monastery on Mahee Island. It was built in 1570 by Captain Thomas Browne. It was abandoned by the early 17th century, and fell into disrepair. In 1923, H.C. Lawlor and the Belfast Natural History and Philosophical Society partly renovated the tower house to avoid further erosion and built a buttress wall to support the northwest corner of the tower.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
