Q: What is your favourite historical place in Britain?
A: Din Lligwy, Anglesey. It is tiny, half a dozen houses and barns.
The village was built in the third century AD, above a spectacular beach. But, like many places on Anglesey, it was hidden away so that sea raiders could not see it.
We lived close by when I was a kid and used to walk through the fields to visit, and I could imagine this little community hiding on the wooded hillside scratching a living from the soil as the Roman Empire receded from the shores of Britain. Incredibly atmospheric.
Q: What is your favourite historical place overseas?
A: I could choose lots of places in Greece, but I am going for Nafplio, in the Argolid.
It has a perfect Venetian square in which the whole city comes to play at night. Old mosques and Islamic bath-houses (all converted now) dot the medieval streets.
The town is dominated by two castles, one of which had a Mycenaean settlement. Mycenae is just a short drive away.
In the summer, one can swim under the ruins of the Mycenaean port of Asini. It is a peaceful place, where you feel the complexity and richness of Greek history.
Q: Where would you most like to visit?
A: Sicily. I’ve never been to Sicily. I’ve recently been writing about the battles of the Roman civil wars around the fringes of Mount Etna, and I have no mental picture of the landscape.
There are marvellous Greek cities, perfect late antique villas with stunning mosaics, medieval cities from the Norman period, and an interesting – if disturbing – modern history.
It has always been a cultural crossroads, between Africa and Europe and between east and west.
