The Palazzo Pretorio is an ancient medieval building from the 14th century in the Piazza del Duomo of Pietrasanta.
It is also known as Palazzo di Perrotto degli Streghi, from the name of the owner, a citizen of Lucca, who sold it to the community.
Since then the Palace was the seat of the Captain of Justice and housed the prisons. Later it was the seat of the Banco dei Vicari, and finally of the Magistrates Court.
In the vestibule and on the façade, as is customary, there are numerous marble coats of arms of the families who over time governed the government of Pietrasanta. The central access portal is in marble and dates back to the 16th century, with 18th century additions.
The palace was remodeled in the 15th, 18th and 19th centuries. For some time it housed a theater hall and today houses some municipal offices.
