The Cathedral of St. Martin of Lucca is a Roman Catholic cathedral dedicated to the Church of St. Martin of Tours of Lucca, Italy. It is the seat of the Archbishop of Lucca. Bishop Anselm began construction in 1063. In the original structure, the towering cylindrical arcades and the exquisite back hall of the bell tower are preserved. The cathedral's nave and half-door were rebuilt in the 14th century in Gothic style, while the western line was started in 1204 by Komo's Guido Bigarelli, with a wide porch consisting of three magnificent arches above three open spaces decorated with sculptures.
