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 secular and domestic architecture
Among the most impressive feats of medieval engineering is bridge construction, "comparable with the great cathedrals of the period". Bridges from this period are characterised by typically Gothic ogival arches. It was not uncommon for such bridges to also provide room for shops, chapels and other structures. This can still be seen at the Ponte Vecchio, Florence (Italy). Other fine examples of still extant medieval bridges are the Pont Saint-Bénezet or Pont d'Avignon, Pont Valentré and Pont d'Orthez, all in France, as well as the famous Charles Bridge, Prague (Czech Republic).
