Mario Botta, Hon. FAIA's entry into ecclesiastical architecture was in 1966 when he designed a chapel at the Capuchin Bigorio Monastery in his hometown of Ticino, Switzerland. Throughout his five-decade career, the Swiss architect has designed more than 100 structures that draw inspiration from some of the great modernists like Le Corbusier, Louis Kahn, Giovanni Michelucci, and Carlo Scarpa and show a preference for materials including stone, brick, and concrete that is also evident in Botta's other work. While he has designed banks, libraries, museums, and residential structures, religious buildings have been the architect's passion. "Church architecture describes visually the idea of the sacred, which is a fundamental need of man," he said in an interview with Judith Dupre for her book Churches (HarperCollins, 2001).

"Sacral Spaces," at the Ringturm Exhibition Centre in Vienna, examines 22 religious projects that Botta has completed across several countries since that 1966 chapel: 18 built, three on-the-boards, and one proposal. The Ringturm exhibition aims to tell the stories of each project, its commissioner, and its community. According to the press release, Botta believes that only completed works can do this, with exception of the chapel in Milan.
