The Castle of Himara dates to the IV – III century B.C. Below the castle were found two bays that were suitable for ship anchorage. Arable lands that are in full contrast with the sharp relied of the coast are found round the castle. The cliff of the castle at the pass identifies with it in the east while in the north west and south if falls over the stream of Visha with its scary spurs. Since the ruins of ancient walls are ruined or covered by new constructions it is difficult to trace them. In the north, near a ruined church there is a partially damaged round well. It has a diameter of 4 m and it is 4.302 m deep. Traces of the castle wall start at the northeast and after a slight turn continue in as straight line. In the southeast the walls makes a strong turn towards a tower with a 6.5 m front side. Constructed with huge stone blocks of different sizes and shapes, the tower is 2 m high. Stone dimensions vary between 1*x 0.90 m up to 0.80 x 50 m. The stones at the foundations of the tower are placed one above the other, while in the upper part they are bound with mortar: 5to 6 m away from the tower there is an Illyrian wall and further the medieval wall which continues up to the church of Kasopitre. The walls are constructed with finely hewn limestone blocks, with enlarged fronts and trapeze and rectangular shapes. The castle has a small area of nearly a hectare but its favorable positions and the wall track over the abysses have made Himara an important and well-protected place. The construction techniques of its walls show the fortified character of Himara in the Antiquity and Medieval period. Studies and research have testified that Himara was a military strategic centre rather than a developed economic centre. Its low development during the Antiquity is explained with its geographical and physical position that did not favor its further development, the lack of good arable lands for the development of rural centers and the historical events in it went through.
Himara old town is located north of the town on the same hill where is located also the castle of Himara. It has a history of two thousand years of being the capital of the entire coastal area till today. In antiquity, the city was known by the name of Chimera. The very first mention of Himara goes as far back as the 1st century from Roman author Pliny.
