Situated on the eastern side of the castle, the Church of Evangelistria is diferent from most of its contemporary churches, and is distinguished for its larger proportions and for a more careful elaboration of its architectural elements. It is composed of the nave, a two story narthex and the portico. The single nave has two entrances, one on the northern side through the portico, and one on the western side, both of which lead to the narthex. The altar area is divided from the nave by a wooden iconostasis which has few original parts in its composition. The apse is composed of the semi-circular raised platform in the center, still covered with frescoes, as well as the two niches serving as prothesis (area for preparation of communion) and diaconicon (area for keeping holy books and vessels). The illumination of the hall, different than the other churches of the castle, is more abundant as a result of the presence of windows on the upper northern and southern wall of the nave. A fight of wooden stairs leads through the narthex into the mafl, which is beautifully and artistically carved on the facade. On the northern side, the nave is preceded by an open colonnaded portico made of circular stone pillars.The whole perimeter of the church, except for the apse, is surrounded by walls. The walls were constructed using lime mortar to connect the stones and beautifully carved stones on the corners. The seven-sided apse is also made of carved stones. Judging from the construction technique, the dimensions and the architectural quality, the church has been dated to the 17th and 18th centuries.
