Mario Botta (born April 1, 1943) is a Swiss architect.
He designed his first buildings at age 16, a two-family house at Morbio Superiore in Ticino. While the arrangements of spaces in this structure is inconsistent, its relationship to its site, separation of living from service spaces, and deep window recesses echo of what would become his stark, strong, towering style. His designs tend to include a strong sense of geometry, often being based on very simple shapes, yet creating unique volumes of space. His buildings are often made of brick, yet his use of material is wide, varied, and often unique.
On January 1, 2006 he received the Grand Officer award from President of the Italian Republic Carlo Azeglio Ciampi.
