The
church is a combination of two architectural types: it is a three-aisled basilica
on the ground floor, and a cross-vaulted church on the upper floor, of the composite,
four columned type, with five domes. The central east apse is five-sided while
the two lateral ones are semihexagonal. To the west is a two-storeyed, domed narthex,
richly decorated with wall paintings of the Palaeologan art of the 14th century.
The good quality frescoes are today partly covered by a later plaster.
The restoration of the monument was carried out in 1972 and the roof
tiles were replaced in 1990. Work for the restoration and cleaning of the wall
paintings has also been undertaken. Today it is the parish church of the village.
The area of Leontarion is full of remains of the Byzantine period,
which indicate that it was of great importance to the Despotate of Moreas. Other
Byzantine monuments to be seen in the area are: the Castle of Leontarion, the
church of St. Athanase (14th century), of the Taxiarchs, of Aghioi Pantes (14th
century), of St. George, of Prophet Elias, of St. John as well as many abandoned
monuments: the Monastery of St. Nicholas, the churches of St. Basil, of St. Kyriaki
and of the Transfiguration of Christ.
