Construction of the Lausanne Cathedral began in 1170. Twenty years later another master mason restarted construction until 1215. Finally a third engineer, Jean Cotereel, completed the majority of the existing cathedral including a porch, and two towers, one of which is the current day belfry. The other tower was never completed. The cathedral was consecrated and dedicated to Our Lady in 1275 by Pope Gregory X, Rudolph of Habsburg, and the bishop of Lausanne at the time, Guillaume of Champvent. The medieval architect Villard de Honnecourt drew the rose window of the south transept in his sketchbook in 1270.
The Protestant Reformation, a movement which came from Zurich, significantly affected the Cathedral. In 1536 a new liturgical area was added to the nave and the colourful decorations inside the Cathedral were covered over. Other major restorations occurred later in the 18th and 19th century which were directed by the great French architect, Eugène-Emmanuel Viollet-le-Duc.
During the 20th century major restorations occurred to restore the painted interior decorations as well as to restore a painted portal on the South side of the Cathedral. New organs were installed in 2003.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. 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.
