Cathedral of San Martino - Situated in the homonymous square, the Cathedral dedicated to San Martino is Lucca`s most important church.

It is a Romanesque church, whose construction began in 1060 and which underwent remarkable reworkings during the 14th and 15th centuries.

The façade is by Guidetto da Como, who in his work was highly influenced by Pisan architecture. The sculptor completed it in 1204. The portico is decorated with reliefs of the "Histories of San Martino" and the "Months" and with other works of art attributed to Nicola Pisano.

The interior of the Cathedral is in Gothic style and is decorated with interesting sculptures, paintings and frescoes.

The Cathedral houses a little temple by Matteo Civitali containing the so-called "Volto Sacro di Lucca" (Sacred Countenance) - an ancient wooden crucifix dating back to the 11th-12th century - and the famous tomb of Ilaria del Carretto, which Paolo Guinigi, the woman`s husband and lord of Lucca, commissioned to Jacopo della Quercia.

Close to the Cathedral stands the bell tower, which was completed in the 13th century and is crenellated like a tower.

Opposite the Cathedral, the Museo della Cattedrale (Cathedral`s Museum) houses vestments and church plate, miniated books dating back to the Middle Ages and works of art.
