Castles in Britain and Ireland

Castles are fortified residences. =Understand= True Castles (those built for defensive purposes) in the United Kingdom were constructed from the start of the Norman Conquest (1066) onward, until the early 17th century when developments in military technology rendered them less effective from a military standpoint. Sometimes the castles were built on or near the basis of early pre-Norman fortifications. Whilst there are true castles in Scotland (notably Edinburgh and Stirling), there are also a number of tower-houses (effectively fortified residences).
