Imagine a museum with no queues, no roped-off exhibits, no glass cases and no slouching groups of bored students. And you could never accuse it of being dry...

Way back in the 5th century BC, an Ancient Greek ship called the Peristera sank just off the coast of Alonissos, a sun-dappled island in the Aegean sea. It was carrying around 4,000 amphora – clay jars traditionally used to make and store wine, which have remained on the seabed ever since.
The wreck site has long been of interest to archaeologists. But now, just 2,000 years after the boozy bounty was lost, the Peristera has been declared open to visitors until 3 October. There's a catch, though: not only will you need to hire an authorised guide, you'll also need to borrow some scuba gear.
