Castello Cova was built between 1910 and 1915 on a design by architect Adolfo Coppedè (brother of the more famous Gino Coppedè), it is an example of Gothic Revival architecture, with guelph-style merlons decorating the external rusticated walls as well as the middle-ages styled tower. The tower of Castello Cova was reportedly an inspiration for the architects of the Velasca Tower, a landmark skyscraper in the centre of Milan. The Pusterla di Sant'Ambrogio, an ancient postern of the Medieval walls of Milan facing Castello Cova, was recreated in the late 1930s in a style that matches the Revival style of the Castello.References:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
