Tourists are not allowed to take pebbles from popular beaches in Greece - or wear high heels at some of its historic monuments.
Visitors could face fines of up to £771 should they commit either of these misdemeanours. It is because the country has introduced, over the years, strict laws to protect its landscape and heritage.
Greeks believe heels can disrupt or damage the old stones at its multiple ancient sites so high heels are banned at these attractions.
