Discover how ancient Roman engineers created structures that have outlasted modern buildings by centuries using ingenious techniques that today's architects still struggle to replicate.
An arch is a curved structural member that spans an opening and supports loads from above, characterized by wedge-shaped blocks known as voussoirs. The central block, or keystone, locks the arch in place, ensuring stability. Arches are renowned for their ability to span wide openings and carry substantial loads, making them integral to architectural innovation.
