Pompeii

 At the entrance to Pompeii.

( apparently the dust from the Volcano would have covered the tallest trees about  30 feet).

 At the Amphitheatre in Pompeii

 The pupils and staff shuffle down the streets of Pompeii

 An empty street with a small bridge over the guttering.(they were quite clever those Romans)

Some people who were unlucky enough not to escape the blast of the volcano.
