France and Great Britain are home to a number of striking examples of gothic architecture built in the twelfth and thirteenth centuries, including cathedrals and castles. On this website, created by Columbia University art historian and archeology scholar Stephen Murray and Vassar College art professor Andrew Tallon, visitors can explore photographs of these structures and learn more about the history of this architecture. On The Main Map, visitors can explore annotated photographs of structures by geographic pin. Many of these pins included multiple photographs, allowing visitors to examine the exterior and interior of structures in great deal from their own computer. The majority of structures are located in modern France, but this collection also includes a large number of buildings in the United Kingdom. Another way to experience the site is via The Historical Maps and Timeline section, which features an animated map outlining the intersections between the history of France and the construction of these buildings. Meanwhile, visitors with a passion for architecture will enjoy the Comparison feature, which allows visitors to layer a variety of exterior and interior architectural features on different structures. A work in progress, the Stories and Essays section provides more information about Gothic architecture as well as the history of France.
