San Lorenzo, also known as the Royal Church of Saint Lawrence, is a Baroque-style church in Turin, Italy. The present building was designed and built by the Italian architect Guarino Guarini from 1668 to 1687. This photograph shows the interior of the church's dome, the base of which is circular, although the lantern above it is octagonal. The dome itself is supported by eight ribs forming a lattice similar to those found in mosques and Romanesque churches in Spain.Photograph credit: Livioandronico2013
