Santo Stefano church is one of the most outstanding examples of Romanesque architecture in Genoa. It was founded in the Middle Ages as part of an abbey, in the place where previously a 6th-century small church, entitled to St. Michael Archangel, was located. The most ancient document mentioning Santo Stefano dates from 965, although some scholars attribute its foundation in 972 to the then bishop of Genoa, Theodulf, who rebuilt it after a Saracen inroad.
It became a parish only eventually, in an unknown date, anyway after 1054. The abbey was held by the Benedictine order of Columbanian monks of Bobbio from 972 to 1431, when Pope Boniface IX turned it into a commenda under Cardinal Ludovico Fieschi. In 1497 a chapel with a marble choir was added to the church. In 1535 the monastery was demolished, replaced by another in the mid-17th century. The abbey was cared by the Olivetans from 1529 until 1776.
Santo Stefano is on a single nave, with a superelevated presbytery. Under the latter is the crypt, which would be the original nucleus of the church of St Michael Archangel. The dome is now in brickwork; it was rebuilt in the 14th century by abbot Niccolò Fieschi, and is octagonal in shape. The lower section of the bell tower is of uncertain dating, but is commonly deemed to be antecedent to the current church, and that it was probably used as a defensive structure.
The old church was to be replaced by a new Neo-Romanesque style edifice from the 19th century. The latter was however almost destroyed by Allied bombings during World War II.
References:The stone church of Gamla Uppsala, built over the pagan temple, dates from the early 12th century. Due to fire and renovations, the present church is only a remnant of the original cathedral.
Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
