The Symphony of Stones or “Basalt Organ” is a natural monument located in the basin of the Azat River, in the area of Garni village. It is included in the list of RA natural monuments. The monument consists of huge symmetric hexagon and pentagon basalt columns (nearly 50 meters high), which seem to be handmade due to their amazing symmetry. These stones hanging against the gravity resemble an organ, which explains why it is also referred to as “Basalt Organ Pipes”.
The Garni Gorge is situated 23 km east of Yerevan, Armenia, just below the village of the same name. On a promontory above the gorge the first-century AD Temple of Garni may be seen. Along the sides of the gorge are cliff walls of well-preserved basalt columns, carved out by the Goght River. This portion of the Garni Gorge is typically referred to as the "Symphony of the Stones." It is most easily reached via a road that leads left down the gorge just before reaching the temple of Garni. Another road leads to the gorge through the village, down a cobblestone road, and into the valley. Once in the valley, turning right will lead to Garni Gorge, an 11th-century medieval bridge, and the "Symphony of the Stones".
