About this app
Welcome to the Hadrian’s fascinating underworld.
In the ancient canals of the Hadrian Aqueduct in Athens, springing from Tatoi to Kolonaki, water has been flowing for more than 19 centuries.
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. You can send your messages to otherusers or for public use.
The wells are scattered all over the city. Connect with the one near your house and play a GPS game by visiting others.
Enter the fascinating world of the underground canals. Play the game.
We recommend Android 8.0 or newer to best experience our app.
