Why the baptistery at pisa was built?

The Baptistery of Pisa was constructed to serve as a place for the baptism of new Christians, reflecting the importance of this sacrament in the medieval church. Commissioned in 1152, it was part of a larger architectural complex that included the nearby cathedral and campanile, symbolizing the city's wealth and religious significance. Its unique round shape and elaborate Romanesque design showcase the artistic and architectural ambitions of Pisa during that period. The baptistery also serves as a testament to the city's role as a major maritime power and cultural center in medieval Italy.
