The abandoned Monastery of the Prophet Ilias at Iliovouni was built in 1720 by the monk Kallistos, its first abbot, and renovated in 1852 by the abbot Dionysios. The wall paintings in its church, executed in 1878, show strong western influences, and its marble icon screen holds interesting icons. The monastery cells were burnt by German occupation troops in 1943 to prevent their use by the Greek resistance; the belfry dates to 1908.

The Castle of Ali Pasha stands on the peak of the hill of the village of the same name near Parga. Built in the early 19th century, it is square in plan and relatively small, and from this vantage point it commanded the region of Parga and the Ionian Sea.

The Monastery of Aghios Demetrios (Tourkobaloukou) lies near the right bank of the River Kokytos, a tributary of the Acheron, in the vicinity of Kypseli village. As a plinth inscription testifies, its church was built by the Despot of Epirus Michail II Doukas in 1242, as was the monastery refectory (Trapeza), later converted into the church of Aghios Georgios. The side chapels were added later and the narthex around the late 13th century.

The Roman Villa at Riza forms part of a larger architectural complex, preserved to a significant height as far as its vaulted roof. It is decagonal in plan, inscribed in a square of 8 x 8.20 m, and its interior is decorated with niches — four on the north and two on the south side — each surmounted by a relieving semi-circular arch.

Ancient Batiae was a colony of the Elians (7th century BC) near today's village of Rizovouni. It was fortified with a polygonal outer wall as well as internal walls, and built on a hill. Parts of the ancient walls and Roman additions still survive. Its inhabitants later moved to Kassope.

Ephyra, the most ancient city in Epirus, lies around 500 m north of the Nekromanteion. It was a Mycenean colony of the 14th-13th century BC, mentioned in the Homeric epics, and was later colonised by the Corinthians. A fairly ruined inner wall survives, and on its inner side two Iron Age children's burials were found.

Today's Kastri is ancient Pandosia, the most important 8th-century BC colony of the Elians and capital of the state of Kassopaia. Built on a hill dominating the whole area, the city was surrounded by walls of around 360 m, with a total length of about 1,640 m, reinforced by 22 orthogonal towers, and had a population of around 10,000.

The fortress of Kiafa rises in the mountains of Souli, above the village of Samoniva. The view from the fort is panoramic: to the west lie the ravines of the Acheron and the plain of Fanari, and from here one grasps the whole mountainous formation of the region. On its west side survives a double wall with vaulted storerooms on the ground floor.
