Ephesus was built in the 10th century BC by Attic and Ionian Greek colonists. Even until today the city is famous for its nearby Temple of the Artemis known as one of the Seven Wonders of the Ancient World. Today you can visit the impressive ruins that have been designated a UNESCO World Heritage Site in 2015.
You are not allowed to ride or take your bike into Ephesus, but you might be allowed to lock it behind the entrance. Just ask nicely.
