2. Excursion of history and adventure in Lavreotiki
Sunday 14 May, 2023

Our destination is the exploitation galleys of one of the largest underground mines of Attica. The chambers of metal extraction, rich in recognisable minerals, combine the mystery of ancient drifts with the beauty of caves. We will wander underground for up to 3 hours and explore the maize of drifts, the chambers supported by natural as well as carved-out pillars and the stalactites decoration reminiscent of natural caves. Each of the routes we follow hides surprises waiting to be discovered! 

After we will visit the great “Chaos” sinkhole, a heart-shaped sinkhole formation 150m in diameter and 55m deep. This chiasm may have been formed by the collapse of a cave roof as many of the area’s mining tunnels end there.

Scientific theme: Underground mining activity in Lavrio

Duration: 6 hours inclusive

Detailed program

9.30-10.30 Athens-Lavrio

10.30-13.30 Underground mines

14.00-14.30 Stop at dolin “Chaos” and return to Athens

14.30 – 15.30 Lavrio-Athens

Cost per person: 40,00 €

*limited participation on a first come first served basis. In case participants are less than 20, the respective event will be cancelled and a refund wil be given.

1. We go down Athens underground. (Athens centre, moving around on foot)
Saturday 13 May, 2023

How many surprises can the Athens underground have in store for its visitors? The stroll will start from underground shelters and detention areas of the German Kommandatur, remnants of the 2nd World War in Athens. Then, we will take the steps that start off under a timeworn trap door on the side of a road or hidden away in a sidewalk flower–bed, that will lead us in a different, forgotten underground area of the city! For hundreds of years, underground pathways have been used for various and mysterious purposes. Some say that all underground pathways are interconnected although there is no proof of this. Nevertheless, the allure of an unknown world is always there, beneath the ground we walk on. We lift up the antiquated hatch and descend the stone steps.  In the catacomb, we come across tunnels of ancient aqueducts, roman baths and byzantine crypts. The Athens river is also found hidden below the ground, running in old galleys under the most central streets of Athens – we can hear the cars passing over our heads! 

We invite you to discover together the hidden secrets of our city!

Scientific theme: underground constructions of the 19th and 20th century.

Duration: Maximum of 4 hours.

Detailed program:

11.00 Meeting outside Metro Station Panepistimio

11.30 Memorial Site (Korai Street). Two-level underground shelter below the Mansion of Ethniki Insurance Company.

13.00 Catacombs of the Russian Church (Filellinon Street). Inside the catacombs a tunnel and a shaft from ancient Peisistratus aqueduct, ruins from roman baths and crypts of the Byzantine order of Likodimos -11th century.

14.00 Ilissos River (area of Panathenaic Stadium). The buried riverbed of Athens river Ilissos.

Cost per person : 35,00 €

*limited participation on a first come first served basis. In case participants are less than 20, the respective event will be cancelled and a refund wil be given.
