One of the most important features of any mosque, a Muslim place of worship, is the space to broadcast the regular call to prayer. In the Middle Ages particularly, this was achieved through building a thin, tall tower at one corner of the mosque. This high tower was called a "minaret" and was often the tallest building in a medieval Islamic society.

La Sagrada Familia was planned as a massive church in Barcelona that would rival its Cathedral in size. After breaking ground in 1882, the church is still not totally finished. Importantly, its architect Antoni Gaudí was killed in a 1926 tram accident, and the work had to continue on under architects with different design aesthetics than its singular original designer.

The Italian architect Andrea Palladio was well known for his own buildings in his native Venice, but gained greater fame for the work of architectural theory he composed in 1570, The Four Books of Architecture. Drawing on Greek and Roman influences, Palladio called for symmetry, domes, columns, and grand spaces. Each of these elements would become hallmarks of neoclassical architecture during the eighteenth century.
