Findlater Castle is the old seat of the Earls of Findlater and Seafield, sitting on a 15m high cliff overlooking the Moray Firth on the coast of Banff and Buchan. The cliffs here contain quartz; the name 'Findlater' is derived not from Norse as earlier stated here, but from the Scots Gaelic words fionn ('white') and leitir ('cliff or steep slope').
The first historical reference to the castle is from 1246. King Alexander III of Scotland repaired this castle in the 1260s in preparation for an invasion by King Haakon IV of Norway. The Vikings took and held the castle for some time. The castle remains that are still there are from the 14th-century rebuilding, when the castle was redesigned based on the Roslyn Castle model.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
