Akrotiri is a sensational archaeological site on the island of Santorini. This is the amazingly well preserved ruins of a town that was buried under volcanic ash about 4,500 BC. Unlike Pompeii the people had enough warning to get out of town in time and no victims of the disaster have been discovered in the ruin. The buildings in Akrotiri are beautiful and very modern in their aspect – including a flushing toilet. The beautiful frescoes that were discovered here have been removed to museums – but you can buy a book from the archaeologists’ book stall near the site. The wikipedia page says it much better than I can – except to say I highly recommend a visit.
