Bewva, you were lucky.
It's 8 TL per person and was that price throughout 2009 after going up from 2 TL per person.
However, if you want to get in for free, use the entrance near Muzzy's, which isn't manned during the winter. Walk around the back of the Poseidon and Antik Restaurants and enter by the Old Church.
OR
You can also get in for free if you go up the track beside the well on the mainstreet, and past the Sarnic Restaurant.
