The Timbrel Vault, original from Islamic architecture, is a remarkable structural technique known for its elegance and efficiency. It involves constructing vaults using a series of interlocking bricks or tiles, forming a self-supporting structure without the need for additional support systems. This method, developed to optimize material usage and reduce costs, made its way to Europe, where it faced initial skepticism in Italy.
However, its fortunes changed when a visionary Fray Lorenzo de San Nicolás reintroduced it to the Spanish court, sparking renewed interest. From Spain, it spread to the Valencian Community and Catalonia, where architect Guastavino refined and elevated its application.
Today, this technique stands as a testament to the enduring legacy of architectural innovation and cultural exchange. This research belongs to Roca: Mediterranean Perspectives.
