Part open part underground building stone quarry. Now a local attraction with an underground theatre/concert hall. Reminiscent of the Bath stone workings. Stone reputedly take from here to Vienna, and reputedly Roman in origin. While not doubting this, it is also very likely that the stone was quarried for the nearby town of Sopron. Location is that blobby bit of ground just to the east of the push-pin - I don't seem to be able to tweak the coordinates to get it precisely right. PB
Following the annexation of Hungary in 1944, German occupying forces established a 'transit/labour camp' in a quarry in Fertorákos, to which Hungarian Jewish and political prisoners were sent, and many thousands died here, with others transported onward to concentration camps in Poland and Germany. The site of the transit camp can be visited, and has a memorial plaque.
From the village website:
Millions of years ago here was the sea. Billions of snails, seashells and small lime-bodied animals formed the Lajta-limestone. The limestone is no longer quarried. Now here in the cave theatre opera performances and concerts are hold in summer. The “Lajta-limestone” is easily formed and resists changeable weather conditions. A great many houses have been built using this type of limestone. Irregularly formed large halls resembling Egyptian temples and big pillars supporting the limestone ceiling captivate visitors.
The core of the Sopron Festival Weeks is the performances in the stone quarry in Fertorákos famous throughout Europe. Performances have been held regularly since 1970. At the very beginning the Sopron Brass Band organized promenade concerts here. The first performance was in summer 1970. An architectural expert’s opinion about the cave theatre is: “the union of the stone quarry’s exterior and interior offers such a spectacle as could only derive from antique architecture”. The excellent acoustics and the wonderful natural surroundings are suitable for arranging musical, dance and opera performances offering a unique experience.
Seating-room of the theatre: 743 persons.
