The key characteristics of Gothic architecture include tall, grand designs with pointed arches, flying buttresses, vaulted ceilings, and ornate decorative styles. Salisbury Cathedral is a prime example of Gothic architecture, with a cross-shaped layout and emphasis on height and light. Its structural system uses pointed arches, rib vaulting, and an extensive system of interior and exterior flying buttresses to support the tall design and cope with the weight of the central tower and spire.
