San Fermo Maggiore is a medieval Romanesque church. A church at this site may has been traced to the 8th century, and by the 11th century a second story and belltower was added by the Benedictine order. The campanile was not completed until the 13th century, it contains six bells in F cast in 1755 and rung with the Veronese bellringing art. The exterior has a roofline with pinnacles, and the church once held the tomb of a member of the Scaligers. The interior has later decoration, including an altarpiece of St Francis of Assisi by Giovanni Battista Belloti. The presbytery hosts relics of the saints Fermo and Rustico.
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.
