The Cathedral of Livorno, dedicated to St. Francis, has a façade completely rebuilt after the bombings of World War II, with a portico with round arches, which some attribute to Inigo Jones, the father of English Renaissance architecture.
The interior is in the shape of a Latin cross, and in the transept are the two side chapels: on the left, that of the Blessed Sacrament, and on the right, that of the Conception of Mary.
The frescoes in both chapels were lost during World War II.
In 2006, on the occasion of the events related to the bicentennial of the Labronica diocese, the Christ Crowned with Thorns by Beato Angelico was placed in the Cathedral.
The Cathedral is accessible from the doorway on the left-hand side of the building through a ramp. The gateway is usually closed and is not easy to open due to its weight and size.
