A 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. Cathedrals are often characterized by their impressive architecture, featuring tall spires, intricate stained glass windows, and elaborate decorations. They are designed to accommodate large congregations and often serve as a venue for significant religious ceremonies, such as weddings and ordinations. Many cathedrals are historical landmarks, reflecting the artistic and cultural heritage of their regions. Notable examples include Notre-Dame de Paris in France and St. Peter's Basilica in Vatican City. Cathedrals often play a vital role in the community, hosting events and providing a space for reflection and prayer.
