The church is dedicated to the Assumption of Mary. It is of unparalleled beauty in the byzantine order. The festival that takes place on the 15^th of August is the biggest in the Peloponnese. Countless people flock to the diocese to honour the Virgin Mary and to be associated with the primeval sanctity of the place. The icon of Mary Mother of God is carried in procession into the park of the Tegea League. Essentially it is an enormous open archaeological site shaded by tall trees.  The whole atmosphere allows the soul to rise up to the skies.

The original church must have been built in the 11^th or 12^th century. It was the cathedral of the medieval town of Niklio. The position coincides with the ancient theatre cavea. The present day’s church was funded by the Tegea League in 1888 since the previous one had collapsed. Until 1851 an unusual custom took place on the surrounding land.

Together with the religious ceremonies there was a festival known as that of Beauty which was dedicated to arranged marriages. Matchmaking was a very ancient surviving tradition, known throughout Greece.
