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.
Ystad
One of Sweden's most well-preserved medieval monasteries, the Greyfriars Abbey, lies in Ystad. The town also has an additional large medieval church, the Church of the Virgin Mary ("Mariakyrkan"). Both are highly influenced by Gothic Hansa architecture (which can also be seen in churches around the Baltic Sea, for instance in Helsingborg, Malmö, and Rostock) and are among the best examples in Sweden of Brick Gothic. In addition, there are areas of surviving medieval town architecture, like the Latin school (built c. 1500) and several town houses. The city is also included in the European Route of Brick Gothic. From the steeple of the Church of the Virgin Mary the Tower Watchman (tornväktaren or lurblåsaren) sounds his horn every 15 minutes from 21:15 to 01:00 to let the people of Ystad know that the town is safe from fire and enemies. The Tower Watchman also says a special line when sounding his horn: "The clock strikes ... (for example twelve). All is quiet! From fire and thieves may God preserve the town!" The tradition has existed since the eighteenth century.
