Nafpaktia county is well known for its wild canyons, its high mountains, its rivers and the rocky soil. In most of the villages of Nafpaktia there have been found traces of ancient settlements. In this area there was developed a remarkable civilization, though to bring it out there should be needed further archaeological investigation.

The Byzantine monuments are unmistakable signs of the continual habitation of the area. Because of the inventiveness and diligence of its residents, the area has developed since the Byzantine era many arts and crafts such as silk industry, tanning, ceramics, woodcarving, goldsmithery, coppersmithery, silversmithery, lime-burning etc. Local architecture, a mixture of Epirote and Cravaritic art, the stone-bridges and the typical watermills are worth seeing. During the Turkish domination, education was developed. Renowned is the School of Lobotina, which was run and protected by the Byzantine family of Kanavei and one of whose teachers was the famous Father Kosmas Aitolos.
