When the Roman Emperors came back from winning a battle, they built a triumphal arch as a monument to themselves. There are several of these monuments in Rome as well as in other parts of Italy, and the general design is that of a big arch at the centre, and a smaller lower arch or doorway on either side. The architect Leon Battista Alberti adapted the Roman triumphal arch to the church facade of the Basilica of Sant'Andrea in Mantua. He used the same pattern of tall and arched, low and square, all down the inside of the church as well. This was copied by many other architects. It was also the first building to use columns in the giant order.
