The Oiselinière estate was, before the French Revolution a 'Seigniory'. It is mentioned as early as 1335 in the charter 'Les Actes'. It spreads over the districts of Gorges and Clisson, and under the feudal system depended on the Seigneurs of Clisson and Pallet. For 643 years, this Seigniory only changed families four times: Maurice le Meigen was the owner, then in 1460 one of this descendants through allegiance, Claude Grézeau took over. His family sold the seigniory of the Oiselinière to Jean Goulet de la Fosse de Nantes in 1613. Louis de la Bourdonnaye acquired the property in 1658. Then in 1767, the seigniory was sold to the ancestors of the Aulanier family (This family made a great contribution in the Second World War, Oselinière being a hotbed of resistance).
The castle is a villa built in Italian style between 1822 and 1835 to enclose a square courtyard dated from the 17th century. The villa, the outbuildings, the orangery and the gallery of 'Les Illustres' are included in the inventory of historical monuments since 1997 and are cited as reference in the inventory 'Clisson or return to Italy.'
To the west of the villa, near the orangery stands a set of architectural interest with six niches on its main facade which are made of circular brick and adorned with busts of famous men. From left to right, we can recognize Olivier de Clisson, Conde, Duquesne, Jean Bart, and Bayard Duguesclin.
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
