In Europe, China and other continents, there is a distinction between a wall surrounding a city and a battle site of soldiers, such as a fortress, and the former is called Stadtmauer in German and a city wall in English and the latter is called Burge in German and a castle in English.
ヨーロッパ、中国などの大陸では、都市を囲む城壁と砦のような武士の戦闘拠点とを区別し、ドイツ語ではStadtmauerとBurg、英語ではcitywallとcastleとして区別する。
