Gothic decorations are a style of architecture and interior design that originated in the Middle Ages. They are characterized by pointed arches, ribbed vaults, flying buttresses, and ornate decorations such as gables. Gables are triangular sections of wall at the end of a building, often decorated with carvings or other ornamentation. This style of decoration is still popular today, and can be seen in many churches, cathedrals, and other buildings.
