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.
Dunluce Castle is a ruined medieval castle located on the edge of a basalt outcropping in County Antrim, and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood.
In the 13th century, Richard Óg de Burgh, 2nd Earl of Ulster, built the first castle at Dunluce. The earliest features of the castle are two large drum towers about 9 metres in diameter on the eastern side, both relics of a stronghold built here by the McQuillans after they became lords of the Route.
The McQuillans were the Lords of Route from the late 13th century until they were displaced by the MacDonnell after losing two major battles against them during the mid- and late-16th century.
Later Dunluce Castle became the home of the chief of the Clan MacDonnell of Antrim and the Clan MacDonald of Dunnyveg from Scotland.
In 1588 the Girona, a galleass from the Spanish Armada, was wrecked in a storm on the rocks nearby. The cannons from the ship were installed in the gatehouses and the rest of the cargo sold, the funds being used to restore the castle.
Dunluce Castle served as the seat of the Earl of Antrim until the impoverishment of the MacDonnells in 1690, following the Battle of the Boyne. Since that time, the castle has deteriorated and parts were scavenged to serve as materials for nearby buildings.
