Piazza Franco Anelli, 5,
Castellana Grotte BA, Italy, 70013

Website

The machine is located out front of the Il Coccio souvenir shop that is diagonal from the entrance to the Grotte di Castellano.

The machine is outside the shop and on wheels, and is only available when the shop is open. The cost is 1 euro and 5 cents. Designs are:
1) 'Padre Rio', bust of him,
2) 'Trullo', building,
3) 'Grotte Di Castellana', Man in a cave with a light on his hat illuminated,
4) 'I Love You Grotte Di Castellana', three hearts.

20 Aug 2024 - I've updated with the correct name and address of the shop, which is Il Coccio
(https://maps.app.goo.gl/8hrxVnHZSwvNYpnQ8).
The machine now accepts 5-cent coins rather than 2-cent, but the designs are the same.
The machine is rolling well with a small tail. Lina
