In antiquity, the Limonlu river was the boundary between Cilicia Campestris and Cilicia Trachea, making Limonlu an important border town. The ruins of the castle is 1 kilometre (0.62 mi) north of the town. Byzantine Emperor Manuel I Komnenos captured the town in 1158, but lost it to the Armenian Kingdom of Cilicia. After Karamanid rule of two centuries, the Ottoman Empire captured the town in the late 15th century.
Like most Mediterranean coastal towns, Limonlu produces fresh vegetables and fruits. The town has specialized in citrus production and in fact the name of the town means with lemon. But lately, tourism has almost replaced agriculture as being the most important economic activity. In 4 kilometres (2.5 mi) Limonlu coastal band, there are many summer houses owned by city dwellers (Turkish: yazlık site). The coastal band is also used for tent camps. Most of the town houses on the other hand, are rented as summer boarding houses.
Middle East Technical University in Ankara has a campus just east of Limonlu (called Mersin–Erdemli campus) used by the Institute/Graduate School of Marine Sciences (Turkish: Deniz Bilimleri Enstitüsü) since 1975.
