The Abbey of Santa Giustina is attached to the basilica which was built in the 520s AD by the Prefect Opilius to house the remains of St. Justina of Padua and of other Christian martyrs of the city. By the 10th century the community has been under the Rule of St. Benedict.
At that point the monastic community undertook renovations of the basilica. In 1110 the abbey was sacked by the troops of the future Holy Roman Emperor Henry V during his invasion of Lombardy, in order to punish the monks for their loyalty to Pope Pascal II. The basilica complex was devastated in 1117 by a very strong earthquake which wreaked havoc throughout northern Italy and Germany. After the basilica and monastery were rebuilt, excavations resumed and in 1174 the remains of the patroness of the abbey was discovered, as were those identified in 1177 as those of Luke the Evangelist.
A period of decline in the observance of its way of life began to develop in the monastic community. The abbey reached the height of its influence under the leadership of Ludovico Barbo. He was successful and the abbey became the nucleus of the Congregation of Santa Giustina, which spread to include monasteries throughout Europe who came under the guidance of the Abbot of Santa Giustina. The congregation later became called the Cassinese Congregation. The abbey developed ties with centers of learning across the continent.
The life of the abbey came to an end in 1797 when, along with all other religious communities, it was suppressed in the occupation of Italy by the French Revolutionary Army, led by Napoleon Bonaparte, which established the Cisalpine Republic in the city. Its artworks and the most valuable collections of the abbatial library were sent to Paris by the occupying forces. The monks were expelled and the buildings and property were sold off in 1810. The cloisters were then used as a military hospital, later as a barracks.
The buildings were returned to the Catholic Church in 1917 and Pope Benedict XV re-established the abbey with all its ancient rights and privileges. The basilica and abbey now have the government status of a national monument and operate under the authority of the Superintendent of Monuments and Civil Heritage.
The building is a Latin cross that extends from east to west. At 118.5 metres long and 82 metres wide, the Basilica of Santa Giustina is seventh largest in Italy. There are three main chapels. The presbytery with the choir, and the two chapels for saints Luke and Matthew that form the transepts. Each has a semicircular apse and are flanked by two chapels. Each aisle has six smaller chapels, square plan. The 26 pillars supporting the roof domes, each dome is set directly on the barrel vaults. The central bays are covered by eight domes covered with lead: the central one, with the lantern, is almost 70 metres high and is topped by a statue of copper depicting Santa Giustina, about 5 metres high. The floor of the basilica was laid between 1608 and 1615 on geometric design, with yellow, white and red marble. There are many pieces of Greek marble, from the Basilica Opilionea.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
