Hisarya is a small town of around 8000 inhabitants and a long history. Because of its hot mineral springs is has been inhabited since prehistoric times. It was a Thracian centre, then Roman. What is remarkable, however, is the extent of the Roman ruins – town walls, amphitheatres, barracks etc. L does a walk with the camera along one section of the perimeter wall. In pre-communist Bulgaria it also had numbers of villas for the wealthy.

On the walls of one of these we notice a plaque to Aleksandar Stamboliyski, Bulgarian Prime Minister from 1919 to 1923 when he was toppled by a military coup, tortured and then executed.

A little later we take a break in the town of Karlovo, walking round the city centre. Some Roma children come into the main square and begin to play around with the fountain. It stops.

L and I look at each other, suspecting a repetition of last year, but there is no-one around, so it appears to be a simple coincidence, a time switch activating automatically.
