Riches were brought from the colonialists into and through Havana as it was a key transshipment point between the new world and old world. As a result, Havana was the most heavily fortified city in the Americas. Most examples of early architecture can be seen in military fortifications such as La Fortaleza de San Carlos de la Cabana (1558–1577) designed by Battista Antonelli and the Castillo del Morro (1589–1630). This sits at the entrance of Havana Bay and provides an insight into the supremacy and wealth at that time.
