Austrian-Slovenian-Hungarian tripoint‎, Border marker at Municipality of Kuzma, Slovenia

The Austrian-Slovenian-Hungarian tripoint is a 387 m hill, the westernmost point of Hungary, whose summit carries a truncated-pyramid memorial column 215 cm tall and 173 cm wide at its base. Each of its three faces bears the coat of arms of one neighbouring country and the date of the ratification of the Treaty of Trianon. A memorial plaque and a square stone record the 27 May 1989 meeting of the mayors of Fürstenfeld, Körmend and Murska Sobota during the dismantling of the Hungarian border fence.

The tripoint shifted here after the 1920 Treaty of Trianon transferred German West Hungary to Austria, forming Burgenland. In 1922 a triangular pyramidal memorial stone was erected on the wooded summit, inscribed with the dates 10 September 1919 (Saint-Germain) and 4 June 1920 (Trianon). During the Cold War the hill lay on the Iron Curtain; it reopened on 27 May 1989 when Hungary dismantled its border fence, and a plaque records the mayors of Fürstenfeld, Körmend and Murska Sobota present that day.

The stone is called Tromejnik in Slovene, Dreiländerecke in German and Hármashatár in Hungarian. Since 1989 three-national meetings have been held at the stone every year, and on 1 May 2004 the three border villages of Felsőszölnök, Kuzma and Sankt Martin an der Raab celebrated the EU enlargement here. The name Hármashatár is also used by a restaurant, a hunting society and music groups in the area.

Visitors can reach the marker by hiking trails from any of the three countries, though they should be ready for uneven ground. The location is not easily accessible for wheelchair users because of the natural paths and hilly terrain.

Because the borders are no longer controlled, a visitor can walk a small circle around the stone and step into all three countries within a few metres. The summit is Hungary's westernmost point, and the stone stands on a 387-metre hill that is also the watershed between the Raab and the Mur.
