The Cathedral of San Andrea, also known as the Cathedral of Amalfi, was built in the tenth century in the town of Amalfi in Campania, Italy, and was later merged with the original two churches into a six-porch and five-hall Roman church, and has been rebuilt many times. Visitors can reach the bronze gate at the entrance of the church by climbing 62 steps, which was installed from Constantinople in the eleventh century, with golden mosaics on the top of the church, and pictures depicting the details of Moorish life on the front and colonnade. The exterior of the church is Sicilian Arabian and the interior is Baroque. The ceiling of the church hall is full of holy paintings, the high altar is guarded by four beautiful pillars, and the apostle St. Andrew's crucifixion is painted in the center.
