At a distance of about 4 km northwest of the village of Stamna, and of 400-500 m from the Acheloos on a low hill that dominates the left bank, are the ruins of two churches, just a few metres apart. The site is close to one of the most important crossings of the river and, according to one opinion, was the seat of the Middle Byzantine Bishopric of Acheloos.
The largest church retains almost its entire height up to its roof. It is a one-room aisled structure with a semicircular apse; a narthex was added on later. It was probably roofed with a gabled wooden covering. On the long sides it has two pilasters each. The wall-masonry is plain, with alternating rows of stone and brick, and has denticulated bands around the arches of the west side’s doorway and windows.
Of the second church, which is about 7.5 m off from the first and larger structure, it is the foundations that are mainly preserved. It was similar in form to the larger one and they were probably built at the same time.
The two churches date back to the Middle Byzantine period, specifically to the end of the 9th century and the first half of the 10th.
