Hidden in the forest near Fertőrákos, between the village and Mörbisch am See (Austria), lies one of the region's most remarkable Roman archaeological sites – the Mithraeum, also known as the Sanctuary of Mithras.
Situated beside the cycling route through Fertő–Hanság National Park, the sanctuary was discovered in 1866 and excavated by Ferenc Storno. Until 1989, it remained inaccessible due to the restrictions of the Iron Curtain. Today, it is a popular destination for hikers and cyclists exploring the area.
Visitors arriving from Fertőrákos can also reach the sanctuary by electric sightseeing vehicle as part of a guided one-hour tour. Since 2001, the site has formed part of the UNESCO World Heritage Site of the Fertő / Neusiedler See Cultural Landscape.
