Château de Quintin was mentioned as 'castellum novum' in 1202 and it was probably a fortified manor built in the late 1100s by Alain de Penthièvre. Geoffroy I Boterel built the first actual castle in the middle 1200s. it consisted of a moat, four gates, curtain walls and towers. The castle was badly damaged in the Wars of Religion (1590s).
The next castle was built as a living residence in 1643 and restored in 1785-1790. During the Great Revolution Château de Quintin was used as a prison. Since 1935 it has been owned by Bagneux family.
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.
