Christian cathedrals are large, important churches that serve as the central place of worship for a diocese, which is a district under the care of a bishop. They are often characterized by their impressive architecture, featuring elements like tall spires, stained glass windows, and intricate stone carvings. Many cathedrals are built in styles such as Gothic, Romanesque, or Renaissance, reflecting the artistic trends of their time. These structures not only serve religious purposes but also act as cultural landmarks and tourist attractions. Famous examples include Notre-Dame de Paris in France and St. Peter's Basilica in Vatican City. Cathedrals often host significant events, such as weddings, baptisms, and religious ceremonies, making them vital to the community's spiritual life.
