The Basilica di San Zeno name rests partly on its architecture and partly upon the tradition that its crypt was the place of the marriage of Shakespeare's Romeo and Juliet. It stands adjacent to a Benedictine abbey, both dedicated to St Zeno of Verona.
St. Zeno died in 380. According to legend, at a site above his tomb along the Via Gallica, the first small church was erected by Theodoric the Great, king of the Ostrogoths. Erection of the present basilica and associated monastery began in the 9th century, when Bishop Ratoldus and King Pepin of Italy attended the translation of the saint's relics into the new church. This edifice was damaged or destroyed by a Magyar invasion in the early 10th-century, at which time Zeno's body was moved to the Cathedral of Santa Maria Matricolare: on May 21, 921, it was returned to its original site in the crypt of the present church. In 967, a new Romanesque edifice was built by Bishop Raterius, with the patronage of Otto I, Holy Roman Emperor.
On January 3, 1117, the church, along with most of the city, was damaged by an earthquake; the church was restored and enlarged in 1138. Work was completed in 1398 with the reconstruction of the roof and of the Gothic-style apse.
Attached to the basilica is an abbey was erected in the 9th century over a pre-existing monastery. Of the original structure, destroyed in the Napoleonic Wars, only a large brick tower and the cloisters survive. It had originally another tower and the abbot's palace. For long time the abbey was the city's official residence of the Holy Roman Emperors. In the 1980s a restoration discovered frescoes from the 12th to 15th centuries.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.
