A church, important for its size and architecture, is located in the village of Lessini, on its eastern side, and dates to the end of the 13th century. It is a three-aisled basilica, with a widened central nave. It has acquired the name of Panagia ‘Lessinitsa’, from a representation of the Virgin Mary in the apse. Originally the central nave was covered with an arch and the side aisles with various domes. The two long sides have undergone various interventions from time to time, that have altered their original form.
The church has three apses, of which the central is high and three-sided, while the side ones are smaller, trapezoidal and raised above the ground-level. It is built of brick according to the cloisonné system and the entire central apse is built with bricks in its upper part. Its eastern side bears interesting and rich ceramic decoration, characteristic of the Despotate of Epirus. The central apse is decorated with various motifs, such as cross-shaped meanders, lozenges, a system of broken lines in the fish-bone manner, denticulate bands, etc. On the central side opens a three-light window, with an arched raised and stepped frame. Around the window is formed a simple arched brick frame, outlined with a double denticulate band. On either side of the window of the central apse are blind architraves, which are also characteristic of the era of the Despotate of Epirus.
