 The name Vierburgenland (Land of Four Castles) was created in 1919 by Odo Rötig, a Viennese resident in Sopron.It was derived from the name of the four "vármegye" of the Kingdom of Hungary (in German "Komitate", 'counties') known in Hungarian as Pozsony, Moson, Sopron and Vas, or in German as Pressburg, Wieselburg, Ödenburg and Eisenburg.After the town of Pozsony/Pressburg (Bratislava) was assigned to Czechoslovakia, the number "vier" was dropped, but the name was kept because it was deemed to be appropriate for a region with so many old frontier castles.
