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 Revival architecture
In 19th-century northwestern Bulgaria, the informal Slavine Architectural School introduced Gothic Revival elements into its vernacular ecclesiastical and residential Bulgarian National Revival architecture. These included geometric decorations based on the triangle on apses, domes and external narthexes, as well as sharp-pointed window and door arches. The largest project of the Slavine School is the Lopushna Monastery cathedral (1850–1853), though later churches like those in Zhivovtsi (1858), Mitrovtsi (1871), Targovishte (1870–1872), Gavril Genovo (1873), Gorna Kovachitsa (1885) and Bistrilitsa (1887–1890) display more prominent vernacular Gothic Revival features.
