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.
Cistercian architecture
In the purity of architectural style, the beauty of materials and the care with which the Alcobaça Monastery was built, Portugal possesses one of the most outstanding and best preserved examples of Early Gothic. Poblet Monastery, one of the largest in Spain, is considered similarly impressive for its austerity, majesty, and the fortified royal residence within.
