Campell Castle was probably begun in the early 13th century for the knightly von Campell family. The first mention of the family is from 1289 when Egeno de Campelle appears in a record. The original castle was a four story bergfried. In the 13th or early 14th century it was expanded with a ring wall, gatehouse, ditches and a drawbridgeon the west side and a residential wing on the east. However, the Campell family died out in the 14th century. In 1389 the Bishopric of Chur recorded that Bishop Hartmann granted lands that used to be the Campell fief to Hans and Gottfried von Ehrenfels. Though the grant probably did not include the castle, because it wasn't until 1418 that the Bishop granted the castle to Hermann von Schauenstein-Ehrenfels.
During the 15th century, the west wall was raised and had a roof added. The original tower had two more stories added and was topped with crenelations. A large cistern was excavated to the north. Around the middle of the 15th century the castle was given to the Ringg family, but in 1500 it was returned to the Schauenstein family, so it is unclear who renovated the castle.
In the 16th century it was once again rebuilt. The west wall and zwinger were roofed over and became a three story palas. The old gate in the west was walled up and a new one was added in the south wall. The west wall was extended northward to protect the castle's flank.
In 1562 the Schauenberg-Ehrenfels sold the castle to Hans Faschau. A few years later, in 1567, he sold it to Hercules von Salis, whose family held the castle for almost a century. During the Bündner Wirren of the Thirty Year's War the castle was damaged by fire. The west palas was rebuilt in 1635, while the east residential wing was abandoned and became a stable.(Bauphase 5) In 1647 the Salis family sold it to the Freiherr von Schauenstein-Fürstenau. By 1700 it was abandoned, but remained in good condition. By 1900, it had fallen into ruin when the Abula line of the Rhaetian Railway was built over the outer moat. In 1932 the Campell family bought the castle. Between 1993 and 1998 the ruins were stabilized, repaired and excavated and they opened to visitors in 2001.
Much of the castle is still standing. The original tower stands in the center of the complex. At the foot of the tower is an arched doorway that leads to the eastern wing of the castle. Both the tower and the east wing have retained their medieval character. The west palas was built after the castle had ceased being a fortification and had become a nobleman's house and so has large windows which would have lit comfortable rooms.References:
Château de Falaise is best known as a castle, where William the Conqueror, the son of Duke Robert of Normandy, was born in about 1028. William went on to conquer England and become king and possession of the castle descended through his heirs until the 13th century when it was captured by King Philip II of France. Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840 it has been protected as a monument historique.
The castle (12th–13th century), which overlooks the town from a high crag, was formerly the seat of the Dukes of Normandy. The construction was started on the site of an earlier castle in 1123 by Henry I of England, with the 'large keep' (grand donjon). Later was added the 'small keep' (petit donjon). The tower built in the first quarter of the 12th century contained a hall, chapel, and a room for the lord, but no small rooms for a complicated household arrangement; in this way, it was similar to towers at Corfe, Norwich, and Portchester, all in England. In 1202 Arthur I, Duke of Brittany was King John of England's nephew, was imprisoned in Falaise castle's keep. According to contemporaneous chronicler Ralph of Coggeshall, John ordered two of his servants to mutilate the duke. Hugh de Burgh was in charge of guarding Arthur and refused to let him be mutilated, but to demoralise Arthur's supporters was to announce his death. The circumstances of Arthur's death are unclear, though he probably died in 1203.
In about 1207, after having conquered Normandy, Philip II Augustus ordered the building of a new cylindrical keep. It was later named the Talbot Tower (Tour Talbot) after the English commander responsible for its repair during the Hundred Years' War. It is a tall round tower, similar design to the towers built at Gisors and the medieval Louvre.Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840, Château de Falaise has been recognised as a monument historique by the French Ministry of Culture.
A programme of restoration was carried out between 1870 and 1874. The castle suffered due to bombardment during the Second World War in the battle for the Falaise pocket in 1944, but the three keeps were unscathed.
