The temple of Apollon Smintheus in the village of Gulpinar with its attractive and imposing structure of marble columns; Balontepe and Hantepe Mounds; Kız Castle and the ancient city of Kolonaia are other sites of historic significance in Ezine.It is within the boundaries of the city on Canakkale and in the municipality of Gulpinar which was called "Kulahli" until 1920's. the temple is located in the garden plot of the town which is nourished by spring water. This could be the reason why the temple was erected in this site in ancient times were plenty of water existed. People of Alexandria Troas had come to consult the oracle of Apollon and the god needed water for prophecy.
The temple was first made known to the world of archaeology by Jean Baptista Le Chevalier in 1785 when he saw some remains of the temple as he was traveling from Lectum-Babakale to Alexandria Troas.
