Seven Sleepers Cave
According to rumour, before the acceptance of Christianity as an official religion, seven young men fled from Ephesus in the 3rd century and took refuge here.
They sealed up the cave and fell asleep, and were woken up 200 years later by an earthquake which broke the seal.
When they awoke and walked into the town, they realised that Ephesus was now an official Christian city.
It was deemed to be a miraculous event, and when the young men died they were buried in the same cave, which is now a Byzantine-era grotto.
The adjacent building is named after them and has a large monument, many rock-engraved tombs, two churches and catacombs.
