The Geschriebenstein, less commonly called the Írott-kő in English sources, is a mountain, 884 metres high, located on the border between Austria and Hungary. It is the highest mountain of the Kőszeg Mountains, the highest point in western Hungary and highest point in Burgenland. Its height is 884 m according to Austrian sources, whereas Hungarian references mostly mention 883 m. The highest point on the Burgenland side of the border is 879 m.
Its former Hungarian names were Fenyőhegy and Szálkő. Its present name can be translated as written stone and is assumably derived from border stones with inscriptions between the properties of the Batthyány and Esterházy families. On the summit, there is an observation tower built in 1913. This stands exactly on the border between Austria and Hungary.
