Among the first towns where it was discovered in the twelfth and thirteenth centuries the existence of the paper, if you want to take for granted the information contained in notarial deeds discussing of the existence of paper products, while not specifying whether these were imported from other places and traded in the above-mentioned places, there were the territories of the Maritime Republics: Amalfi, Pisa, Genoa and Venice who had warehouses both in Syria, both on the coast of Palestine, where they were precisely located the major centres for the production of paper. These republics also had intense trade relations with the East and they could learn from the Eastern art of making paper without too much difficulty, or it is possible that on board the galleys, which in medieval times shuttled between our coasts and the Holy Land to transport crusaders and merchandises, they are embarked "Magisters in art cartarum" which as skilled labour have introduced this type of work. Amalfi is the oldest of the Maritime Republics, as early as the ninth century had its warehouses in Palermo and Messina and Syracuse, where the Amalfitana is still present in local place names. Age-old remains the question on the primacy of paper in Italy and then in Europe and in contention are mainly Amalfi and Fabriano. https://www.livesalerno.com/paper-museum

Built in the 11th century with support from the Rufolo family, the Duomo is a combination of Baroque and Romanesque styles. Dedicated to St. Pantaleone, the church has undergone extensive modifications and restorations over the past 900 years. The Duomo’s shining white façade dates back to the last major restoration in 1931. The Duomo’s bell tower, which dates back to the 13th century, shows Moorish and Byzantine influence. Today, the Duomo is primarily remembered for five attractions: The first is the bronze door, which was temporarily removed for restoration in 2010. Constructed in 1179 by Barisano da Trani, the door is of special interest because fewer than two dozen bronze church doors are still extant in Italy, three of them by Trani. The second item of special note is the pulpit, which is supported by six spiraled columns sitting atop marble lions. Across from the pulpit, to the left, is the Ambo of the Epistles that boasts two wonderful mosaics of Jonah and the Whale. The fourth area of special interest is the Chapel of St. Pantaleone the Healer, a 3rd century physician who was beheaded, on orders of the Emperor Diocletian, after he converted to Christianity. The Chapel has a small ampoule of the saint’s blood, which is said to liquefy every year on July 27th, the anniversary of his martyrdom. The chapel also has a silver bust of the town’s venerated saint. The final attraction is the cathedral's museum, which is accessible through a side entrance on the Via Richard Wagner. https://www.ravello.com/attractions/duomo/
