The earliest records of Kõljala manor date to 1509. Traces of the oldest construction have been preserved in the cellars, and these date to the 17th century.
In those days the manor belonged to Otto von Poll, a leader of the Saaremaa German nobility. His lifestyle was somewhat different from the rest, and this was reflected in the furnishings of the manor house. Although the house itself was of one-story limestone construction, it is known that the rooms were lit by ten brass chandeliers, the curtains at the windows had golden fringes, and there were twelve large Flemish carpets hung on the walls.
In 1677 the new owner, J. von Osten-Sacken, had two large brass cannons placed in front of the manor. These he had received as a gift from the Swedish king, Karl XI. The cannon were still there at the beginning of the 20th century.
The next extensive reconstruction and building period took place during 1760-1770. Maps and charts dating from 1784 picture the manor very similar to what it looks like today, a single-story building with a hipped roof and three chimneys. In the middle of the 19th century, the new owner F. W. von Buxhoevden added further "improvements" to the building in the form of then-popular classisistic details, such as the portico with four Ionian pillars.
The classisistic style continued in the landscape design that surrounded the manor house. Full-grown, mature trees formed the backdrop for the house, and on the south side among the trees there were placed three arched gate buildings. Unfortunately, only one has survived.
Today Kõljala manor stands in private ownership.
The Château des ducs de Bretagne (Castle of the Dukes of Brittany) is a large castle located in Nantes. It served as the centre of the historical province of Brittany until its separation in 1941. It was the residence of the Dukes of Brittany between the 13th and 16th centuries, subsequently becoming the Breton residence of the French Monarchy. Today the castle houses the Nantes History Museum.
The restored edifice now includes the new Nantes History Museum, installed in 32 of the castle rooms. The museum presents more than 850 objects of collection with the aid of multimedia devices. The castle and the museum try to offer a modern vision of the heritage by presenting the past, the present and the future of the city. Night-time illuminations at the castle further reinforce the revival of the site. The 500-metre round walk on the fortified ramparts provides views not just of the castle buildings and courtyards but also of the town.
