Therma Spa

Therma Spa sits on the eastern shore of the Gulf of Gera on the Greek island of Lesvos, where a certified natural thermal spring has drawn bathers since antiquity. The waters were renowned in ancient times as therapeutic baths, and by tradition Lesbian women once used them to prepare for beauty competitions held at a nearby temple dedicated to Hera. Today the site combines its preserved historic bathhouses with a modern spa and wellness offering.

The thermal-mineral water and its source

The thermal water begins its journey from roughly 2,500 metres below the earth's surface and rises to the surface as artesian water at about 39.5C. From the certified thermal spring it is led directly into the pools of the bath without any additives, processing, or impurities, preserving the natural properties of the source.

A historic bathhouse

The spa preserves an unusually rich bathing history:

• In the 18th century Captain Housein Pasa built a reservoir able to accommodate 10 to 12 bathers and renovated the structures where visitors waited.
• Travellers recorded its reputation: Olivier G. noted in 1794 that locals considered the waters invigorating for chronic ailments, and J. Dallaway observed in 1797 that Turkish women visited the springs when ill.
• In the late 1800s an upper floor was added above the main bathhouse, serving as a hotel and reception area, with a two-storey building nearby used to store salted goods; further construction followed in the 1920s.
• The upper floors were later demolished and the ground level with its original tanks was reinforced with concrete, preserving two Ottoman-era bathhouses with their characteristic domed architecture.

A 1951 Royal Decree officially designated the spring "THERMA" as a thermal spring, a status again recognised by government decree in 2019. Private operation of the site began in 2015.

Pools and baths

• Traditional stone baths - separate baths for men and women, fed by a natural and continuous flow from the certified thermal spring at 39.3C, with no additives or processing (up to about 10 people).
• Outdoor mixed pool - an open-air pool with sea views, filled with thermal water without additives (up to about 12 people).
• Private bathtubs - individual spaces for 2 to 4 people, with the option of hydro-massage.
• Hot tubs - three jacuzzis offering hydro-massage therapy.

Spa and wellness

Alongside balneotherapy, the spa offers a range of relaxation and massage treatments:

• Aromatherapy massage combining aromatic essential oils with traditional massage, using almond oil and customisable essential-oil blends (30 or 55 minutes).
• Swedish massage, a full-body massage using tapping, kneading and vibration to relieve muscle pain (about 50 minutes).
• Indian head massage, a holistic treatment focused on the head, neck and shoulders using specially blended oils and Ayurvedic principles (about 40 minutes).
• Deep tissue massage, targeting circulation and lymphatic drainage to remove metabolic waste, particularly suited to athletes (about 50 minutes).
• Prenatal massage, a soothing treatment with natural oils for expectant mothers (about 30 minutes).
• A sauna experience using dry high heat with light humidity for toxin removal and rejuvenation, which can be combined with other services.

Setting on Lesvos

The complex lies at the 7th kilometre of the provincial road from Mytilene to Kalloni, on the coast of the Gulf of Gera. The outdoor pool looks out over the sea, and the surrounding landscape of seaside views and natural beauty is one of the site's three signature themes, alongside healing and relaxation.
