The subject of this work is the monastery of Saint Antony in the area of ‘’Petali’’ in Heraklion of Crete, near the village of Kato Assites. The monastery of Saint Antony legally belongs to the near monastery of Saint George of Gorgolaini and it was founded by the time of Venetian sovereignty in the region of Crete, among 15th and 16th century. Today we can find only ruins from the buildings of the ancient monastery and more specifically of the church and the cells. The temple of the monastery consists a very interesting subject of research and offers a wide field of static problems to study due to the variety of damages that characterize its actual situation. This study includes the following stages. Initially includes the collection of all the necessary historical information that comes from bibliographic and personal research. Then follows a detailed documentation and recording of the damages of the temple so that we can classify and study in details all those elements that compose the existing situation of the temple [measurement of all the existing walls of the temple, revelation and numeration of architectural members from the inside and outside of the temple, separation of the different chronological periods of construction of the temple, etc.] Further we analyze the methods of conservation and restoration that we found necessary and we evaluate the actual pathology of the temple. We also propose a partial restoration of the temple by the placement in their initial place of identified architectural members, where this is possible. It is also examined the initial static function of the temple and the possible reasons that contributed to its collapse. Finally in the same time with the proposition of restoration and partial rebuilding of the identified architectural members, we propose the construction of a metal shelter in northern aisle of the temple [this temple is constituted by two aisles] for the better protection of departments that is maintained today even in a form of ruin.
