Catalan Vault

A Catalan vault, also known as a timbrel vault or “boveda de raspall” in Catalan, is a type of architectural vault structure commonly found in Catalonia, Spain. It is a unique construction technique that uses layers of small, flat tiles or bricks arranged in a herringbone pattern to create a curved, domed ceiling or vault. The Catalan vault is a popular building method in traditional Catalan architecture due to its strength, durability, and fire-resistant qualities. It is also relatively easy to construct and requires minimal formwork, making it an affordable option for many buildings.
