Cathedral doors are a type of door that features a rounded arch at the top. They are often used to add a touch of elegance and sophistication to entryways or as decorative elements on cabinet doors. The origins of cathedral doors can be traced back to medieval times, when arches were used to distribute the weight of heavy quarried stones in buildings. This design helped doors and windows to function properly despite the weight of the stones.

Over time, cathedral doors have evolved from functional to purely ornamental. Today, they are often made from a variety of materials such as wood, metal, or glass. While some cathedral doors retain their traditional rounded top, others feature rectangular panels with an arched raised panel added to them. These types of doors are crafted using hand tools and routers, and are commonly found in the inventory of cabinetmakers. Whether they are used as an entryway feature or added to cabinet doors, cathedral doors add a touch of timeless elegance and beauty to any space.
