Sarzana Cathedral (Italian: Concattedrale di Santa Maria Assunta di Sarzana) in Sarzana, Liguria, Italy, is a co-cathedral of the Diocese of La Spezia-Sarzana-Brugnato. It is dedicated to the Assumption of the Virgin Mary. The building is a mixture of the Romanesque and Gothic styles, reflecting the length of the period of its construction, from the early 13th to the late 15th century.
The cathedral is noted as the home of a relic of St Andrew[1] and of the Blood of Christ. There is also an important Romanesque Cross of Maestro Guglielmo of 1138.
