A Roman Catholic Cathedral is a large and important church that serves as the central place of worship for a diocese, which is a district under the care of a bishop. These cathedrals are often characterized by their grand architecture, featuring tall spires, intricate stained glass windows, and elaborate altars. They play a key role in the spiritual life of the community, hosting major religious ceremonies and events. The term "cathedral" comes from the Latin word "cathedra," meaning "chair," which refers to the bishop's throne located within the church. Roman Catholic Cathedrals can be found worldwide, with famous examples including St. Peter's Basilica in Vatican City and Notre-Dame de Paris in France. Each cathedral reflects the local culture and history, making them significant landmarks in their respective cities.
