Aegina island is home to a fine collection of monasteries and churches that reflect the ancient history of the island with many myths about the saints. Religious festivals are organized throughout the year, but the most important takes place on the feast day of Agios Nektarios, on November 9th.

The Holy Trinity Monastery of Agios Nektarios stands on a hill, in the medieval village of Paleochora 6 km from the main town. It was named after its founder, the monk Nektarios who lived in the monastery until his death in 1920. As for today, the active female monastery is visited by thousands of faithful every year and includes many chapels and buildings.
