The Temple of Garni
The Temple of Garni is the sole Greco-Roman temple in Armenia and the former Soviet Union, and is located on a triangular cliff above the Garni Gorge with the famous basalt columns.
The temple is thought to have been constructed in the 1st century AD and was probably dedicated to Mihr, the deity of light in Armenian mythology.
It is still unknown why this temple wasn't destroyed after Armenia converted to Christianity, but some say that it was actually a tomb and not a temple and therefore wasn't destroyed by the newly converted Christians.
The temple was once part of a summer palace complex, and next to the temple ruins of a 7th-century church can be found.
