Pisa - Duomo di Santa Maria Assunta

The construction of the "Duomo" began in 1064 by the architect Busketo, who set the model for the distinctive Pisan Romanesque style of architecture.

When the construction of this cathedral started, Pisa was on a height of political (and financial) power. Pisa was an important commercial centre controlling large parts of the Mediterranean merchant fleet and navy.

In 1017 Pisa had militarily supported the Sardinian "Giudicati" (regional kings) to defeat Saracen troops in the north of Sardinia. Between 1030 and 1035, Pisa defeated rival towns in Sicily. In 1051–1052 Jacopo Ciurini conquered Corsica. In 1063 Giovanni Orlando took Palermo from the Saracen. The gold treasure taken from the Saracens in Palermo allowed the Pisans to start the building of the cathedral.

The bronze doors of the cathedral´s Porta San Ranieri survived the fire, that severely damaged the cathedral in 1595. The doors were sculpted by Bonanus of Pisa around 1180.
