Just outside town, you’ll spot the Elephant Rock, a limestone formation that, well, looks just like an elephant. It’s not just a quirky sight—it’s got archaeological importance too.
The rock holds ancient cave tombs called Domus de Janas (“Fairy Houses”), carved by prehistoric people around 3,000-2,500 BCE. Touching those walls, shaped by hands over 4,000 years ago, honestly blew my mind.
