Today’s pictures are from one of the most fascinating countries I visited. When I went to Azerbaijan, in 2015, I had no idea what to expect. I thought Baku, on the Caspian, would be interesting but nothing prepared me for the splendour of its sights, from the Maiden Tower to the elegant buildings of the first oil book. There were mud volcanoes nearby which we went to on our first morning, quite extraordinary. Then there was Shaki where we stayed in a beautiful old caravenserai converted into a hotel and saw the most exquisite palaces. We also took a plain to Nakchivan cut off from the rest of the country, with its hill monuments. And on the last day we had a cruise on the Caspian to look back on the flames above the city of an idiosyncratic contemporary building.
