Grotta dei Pomodori

The red of the Tomato Grotto, on the other hand, is due to the typical molluscs that with their shape similar to tomatoes surround the walls of the cave giving it a cheerful and original appearance. But the Gargano promontory also has numerous marine watchtowers that have been inserted in some locations on the coast not for strictly defensive purposes, but for reporting the danger of invasions of Saracen pirates.
