The COINS summer school 2021 will host a range of lectures by established as well as upcoming experts in the field.

Important dates:

Summer school: Monday 14/6 to Friday 18/6 online

Location: online (unfortunately not in Greece this year)

kveldssamling_large_fullwidthThe University of Agder’s (UiA) study centre in Greece is located in a monastery annex which forms part of the well-known Limonos Monastery, on the island of Lesvos in the Aegean Sea. As a monastery annex Metochi was founded in the 16th century, and it has been renovated for seminars and study purposes in recent times. The monastery and study centre is characterized by simplicity, good opportunities for studies and reflection, and a traditional Greek kitchen. Metochi has its “agora” – a small “amphitheater” – for the good dialogue, a library for private studies, a lecture room for the good monologue, and a small courtyard and garden for thought and reflection.

Limonos, the main monastery, is a cultural centre in the Northeast Aegean. It was founded early in the 16th century, and holds great treasures from the Byzantine period. The monastery is central in the Byzantine tradition, and it was also important in the Greek people’s fight for independence almost a century ago.

Lesvos is the third largest island in Greece. It is about 100 km long and 50 km wide, and has approximately 125.000 inhabitants. The surroundings are beautiful, with a diverse flora and fauna. The monastery is located in the countryside 4-5 km away from the sandy beaches of the bay of Kalloni.

Metochi Study Centre is located in a monastery dedicated to two Greek Orthodox saints, Saints Anargyroi (Kosmas and Damianos). The monastery was founded in the 16th Century as one of several annexes to the well-known Limónos Monastery. The monasteries are connected by a stone path from the same time period, stretching two kilometres over the hills. The annex Metochi has been restored in recent years, but is still characterized by its original simplicity.

Metochi study centre houses 25 bedrooms, 13 showers, 9 toilets, auditorium/lounge, library/reading room, dining hall, courtyard and churches. The conditions are simple with bedrooms for 1-4 persons in old monk cells. The bedrooms are modestly equipped. Rooms might have fans, but are not air-conditioned.

(If you prefer to stay in a hotel, you can do so in Kalloni, e.g. at Hotel Malemi. Please note that COINS does not cover hotel accommodation outside of the study centre and that you would have to organise your own transfer between hotel and the study centre.)

The monastery is situated in the countryside by the bay of Kalloni, approximately one hour’s drive from the airport. The nearest town, Kalloni, is 3 km from the monastery. Kalloni is a local trading centre with banks, a post office, medical assistance, pharmacies and different shops. The sandy beaches of the bay of Kalloni are at a distance of 4,5 km from Metochi. By the beach is a small fisherman’s village, Skala Kalloni, with hotels, taverns, restaurants and bars. The landscape between the monastery and the villages is flat and well suited for bike rides.

The monastery is not in daily use by the church, but there are still restrictions as to activities and clothing. Participants are advised not to wear clothes equivalent to bathing outfits within the monastery walls. While visiting the main monastery Limónos, shoulders and knees should be covered.

Regular standard: Breakfast (0800-0900), lunch (1300-1400) and dinner (warm meal, 1900-2000) is included, with beverages (juice and wine) during the meals. The participants are provided with sheets (but not towels).

We recommend bringing a flashlight for dark nights and a sunhat for use during bike rides and excursions.

The participants are responsible for being covered by their own travel insurance. Those who have a European Social Security Card should bring it.

There is internet access and Eduroam most places at Metochi.


Participation free of charge, registration required.
COINS students/faculty: COINS covers travel and accommodation using the least expensive practical alternative. COINS will book hotel rooms in Athens for those visiting ENISA. You need to pay for travel and will be reimbursed later following the usual procedures. The hotel in Athens and the Metochi study centre are being paid for by COINS centrally. Depending on the total number of participants, students may need to share rooms (though most probably everybody will have a single room). If you have preferences on sharing, please let us know.

SWITS/COINS partner students: COINS covers travel and accommodation under the same conditions as for COINS students. The offer is limited to a certain number of students. Students need to write a travel report reflecting on their experience and need to send us a picture of them wearing a COINS t-shirt in a summer school session.

Other students/faculty: COINS covers accommodation at Metochi under the same conditions as for COINS partner students, but participants have to cover their travel themselves. In addition, a fee of 300 EUR is to be paid for the week (Sunday-Sunday). If you would love to attend, but could not because of a lack of funds, please get in touch with us. We have a limited support budget for students that do research in the field and who make a compelling case on why their attendance would contribute to the summer school.
