History+
The temple's origins date back to the 4th or 3rd century BC, as evidenced by foundation remains. The building visible today was erected around 100 BC and underwent its first restoration in the 1st century AD. The temple's preservation is due to its conversion into a Christian church around 872, which was dedicated to Saint Mary Aegyptiaca in the 15th century.
