At the bottom, the coat of arms shows three green peaks in the Siebengebirge, the Löwenburg, Lohrberg, and Großer Ölberg. On the middle one of these is superimposed the red and silver checked arms of the Amt Löwenburg, to whose governmental and judicial sphere Aegidienberg belonged for as long as it was in existence. Above that the symbol of Aegidienberg, the Romanesque tower of St. Aegidius' church, is depicted in silver on a red ground. The coat of arms was approved by the district council in its 44th session on 4 November 1963 and certified by the Interior Minister of the State of North Rhine-Westphalia on 16 July 1965. It is still used by local organisations.
