Gothic architecture
Sens Cathedral (begun between 1135 and 1140) was the first Cathedral to be built in the new style (St. Denis was an abbey, not a Cathedral). Other versions of the new style soon appeared in Noyon Cathedral (begun 1150); Laon Cathedral (begun 1165); and the most famous of all, Notre-Dame de Paris, where construction had begun in 1160.
Gothic architecture
Between the 13th and 16th centuries, Gothic cathedrals were constructed in most of the major cities of northern Europe. For the most part, they followed the French model, but with variations depending upon local traditions and the materials available. The first Gothic churches in Germany were built from about 1230. They included "Liebfrauenkirche" ( ca. 1233–1283) in Trier, claimed to be the oldest Gothic church in Germany, and Freiburg Cathedral, which was built in three stages, the first beginning in 1120, though only the foundations of the original cathedral still exist. It is noted for its 116-metre tower, the only Gothic church tower in Germany that was completed in the Middle Ages (1330).
