The Cathedral of Saint Peter of Beauvais in France is one of the oldest and most remarkable churches in the world. This stunning 157-foot architectural masterpiece is twice older than the United States of America.

The construction started in 1225 where skilled stonemasons worked their hardest and fastest to build the highest-vaulted cathedral in all of Europe.

In 1284, construction of the cathedral was stopped when much of its roof collapsed in on itself. It was a major setback but the workers were just as determined to finish the structure, so working on the massive Gothic design resumed. The work came to a halt once again around the mid-1500s due to the Hundred Years War.

The church's construction may have began hundreds of years ago even to this day it has yet to be deemed finished. It's an art piece that's still considered a work in progress. With the quality of work put into the construction of the cathedral, you're bound to notice many of its incredible features. However, one jaw-dropping "detail" of this architectural masterpiece definitely stands out from the rest.

Now, between the masterfully crafted wood, stone, and glass, is one amazing element of the church. This 150-year-old astronomical clock stands out from the rest.

This gorgeous piece, called the Beauvais astronomical clock, was the work of master clockmaker Lucien Auguste Vérité. The clock was finished in 1868. It took Vérité two years to finish the clock.

The clock has 52 dials which track the rising and setting of not only the sun but the moon as well.

What's even more impressive? The dials also track the position of planets, the ocean tides, and the current time in 18 different cities around the world.
