S. Costantino Thermis

About

The Church of Saint Constantine (Agios Konstantinos) at Thermi stands as a testament to the enduring Christian heritage of eastern Lesvos. The Thermi area, located along the northeastern coast of the island not far from Mytilene, has been inhabited since antiquity and is known for its thermal springs — a resource prized since ancient times and still appreciated by visitors today. The Italian rendering of the saint's name, "S. Costantino," reflects the linguistic legacy of the Genoese Gattilusio family, who ruled Lesvos for over a century before the Ottoman conquest in 1462, leaving traces of their presence in local place names and church nomenclature across the island.

Dedicated to Saint Constantine the Great, the first Christian Roman Emperor, the church shares its feast day with his mother Saint Helen on May 21st — one of the more widely celebrated name days in Greece. Churches bearing this dedication are typically among the most active in their communities, hosting liturgies and local panegyria that bring together residents and visitors alike for prayer, music, and traditional celebration. The church at Thermi would serve the surrounding community as both a place of worship and a focal point of local identity, as is common with parish churches throughout the Aegean.

Visitors to this part of Lesvos will find the Thermi area a rewarding detour from Mytilene, combining the spiritual quiet of village churches with the area's wider charms — its coastal setting, historic baths, and the unhurried pace of daily life that characterizes the island's smaller settlements. Whether one comes to attend a feast-day service or simply to admire the modest architecture typical of Orthodox churches in the eastern Aegean, the Church of Saint Constantine offers a genuine glimpse into the living religious culture of Lesvos.

Before you go

What to expect

The whitewashed church sits in the village of Thermi, where sea air mingles with the mineral warmth drifting from the nearby thermal baths. On May 21st, the feast of Saints Constantine and Helen draws residents and visitors for a solemn liturgy and an outdoor panegyri — candles, chanting, and tables set under the trees. Outside of feast days it is a quiet, lived-in parish that feels untouched by tourism.

Best time to visit

May is the highlight for the feast day celebration; spring and early autumn are ideal for exploring the Thermi area without summer heat and crowds.

How to get there

Thermi is about 10 km north of Mytilene along the northeastern coast road — roughly a 15-minute drive through a string of small villages. The church is easily found on foot once you arrive in the village center.
