Modern Angeln , also known as Anglia (German and English: Angeln , Danish: Angel , Latin: Anglia ), is a peninsula in Southern Schleswig in the northern Schleswig-Holstein, Germany, protruding into the Bay of Kiel. It is separated from the neighbouring peninsula of Schwansen (Danish: Svans or Svansø ) by the Schlei inlet, and from the Danish island of Als by the Flensburger Förde ("Firth of Flensburg"). Whether ancient Angeln conformed to these borders is uncertain. It may have been somewhat larger; however, the ancient sources mainly concur that it included the territory of modern Angeln.
