Messages under the city

Welcome to the Hadrian’s fascinating underworld.

In the ancient canals of the Hadrian Aqueduct, springing from Tatoi to Kolonaki, water has been flowing for more than 19 centruries.

The messages of the city flow here,too.

You can read messages that end up in your tank or messages that just flow right under your feet.
