It is not known when Radkersburg was first settled or where the first settlement was located. It is also not known when Radkersburg fell under princely territorial rule. Most likely, Radkersburg originally did not belong to the Duke of Styria, but to an aristocrat to whom it had been given by the king. Contemporary research suggests that Radkersburg was not founded by Ottokar II of Bohemia (1232-1278), but by Albert I of Habsburg (1255-1308). The appearance of the city today is apparently based on a precise plan. Radkersburg was surrounded by a wall with towers in the end of the 13th century. It was elevated to an imperial fortress in 1582 by the Reichstag of Augsburg. Oberradkersburg (Gornja Radgona), on the other side of the Mur river, has been a part of Slovenia since 1919. The bridge across the Mur was reopened on October 12, 1969 which led to rapprochement between Austria and Yugoslavia. A thermal spring was made accessible in 1978, soon followed by an extension to the bathing site.
