It’s tree-mendous. Hidden away in an archaeological park near Naples, Italy, a wild fig tree has been growing upside-down for decades. Its roots are embedded in the ceiling of an archway, meaning the plant’s branches - which sometimes bear fruit - hang towards the ground.

This strange tree is set in the modern-day town of Bacoli, the site of the lost town of Baiae, which is often referred to as Las Vegas for the uber-wealthy of ancient Rome - a hedonistic weekend break destination. Most of the ancient town – which lies near Naples - is underwater today, but the parts of it remain on land and can be explored in the Parco Archeologico delle Terme di Baia.
