Saint-Malo Cathedral (Cathédrale Saint-Vincent-de-Saragosse de Saint-Malo) is a Roman Catholic cathedral dedicated to Saint Vincent of Saragossa. It was formerly the seat of the Bishop of Saint-Malo. The cathedral was built in 1146 when Jean de Châtillon, Bishop of Aleth, transferred his bishopric to the growing town of Saint-Malo on a more secure site across the river. The Benedictine monastery of Saint Malo, founded in 1108, became the home of the bishopric and its church the new cathedral, replacing Aleth Cathedral.
Saint-Malo Cathedral has undergone several transformations so you will see Romanesque, Gothic, High Gothic and Renaissance styles. However, in 1944 during a battle for the city the cathedral was bombed and the choir section collapsed. It took over 20 years to make the repairs.

From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
