Beauvais Cathedral, also known as the Cathedral of Saint Peter of Beauvais, is a Gothic cathedral located in the city of Beauvais in northern France. It is famous for its soaring vaulted ceilings and the intricacy of its Gothic architecture.

Construction of the cathedral began in the 13th century and continued through the 16th century, although it was never completed. The cathedral was intended to be the tallest building in the world, with a planned height of 162 meters, but due to various structural issues, it was never fully completed and currently stands at a height of 48 meters.

Despite its incomplete state, Beauvais Cathedral is still an impressive structure. Its interior features stunning stained-glass windows and intricate stone carvings, including a number of decorative sculptures and bas-reliefs. One of the most notable features of the cathedral is the flying buttresses that support the exterior walls, which are among the largest and most complex of their kind in the world.

Beauvais Cathedral is also known for its impressive astronomical clock, which was installed in the cathedral in the 19th century. The clock is renowned for its accuracy and is still in operation to this day. The cathedral is also home to a number of other historic artifacts, including a collection of tapestries and an impressive collection of medieval manuscripts.
