Enland has seen the most influential developments, through Ireland, Scotland and Wales. They have each fostered unique styles and have played leading roles in the international history of architecture. British architecture begins with the first Anglo-saxon Christian churches after Augustine of Cantebury arrived in Great Britain in 597. Castles and Churches were built on a vast scale throughout the country from the 11th century onwards to help impose Norman authority upon their dominions. English gothic Architecture, which came from France, flourished from 1180 to around 1520. Throughout the United Kingdom, Medieval Architecture has left a legacy of large stone castles, mostly on the Anglo-Scottish border dating back to the Wars of Scottish Independence in the 14th century. The invention of gunpowder and cannons made castles redundant and soon after came the English Renaissance, which brought up new artistic styles of architecture such as Tudor style, English Baroque, Queen Anne style, and Palladian. Georgian, Scots Baronial and Neoclassical architecture advanced after the Scottish enlightenment. In the 1930's various modernist styles of architecture appeared.
