Meaux Cathedral construction began between 1175-1180, when a structure in Romanesque style was started. Defects in the original design and construction had to be corrected in the 13th century, in which the architect Gautier de Vainfroy was much involved. He had to remove the previous cathedral almost totally and start a new structure in Gothic style. In the later 13th century work was often interrupted due to lack of funds, a problem removed by the generosity of Charles IV in the early 14th century. Further progress was interrupted by the Hundred Years' War and occupation by the English.
The archives of the diocese were destroyed in 1793 – 1794, thus deleting much knowledge about the early history of the church. The composer Pierre Moulu worked at the cathedral in the early 16th century.
The design of the cathedral, because of its construction period, encompasses several periods of Gothic art. The cathedral rises to a height of 48 meters; inside, the vaults at the choir rise to 33 meters. The interior ornamentation is noted for its smoothness, and the space for its overall luminosity. The cathedral contains a famous organ, built in the 17th century.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
