Thank you for sharing your beautiful picture and wiki link. I've only been to Sofia once but I wanted to see so much more of Bulgaria, as it looks like a beautiful country. Your photo is prove of that
Thank you for your kind words but it’s not my photo, it made by Vladislav Terziiski, here’s his Instagram if you want to see more. If you come to Bulgaria again I would recommend you to visit Plovdiv, it’s the oldest continuously inhabited city in Europe and it’s full of history.
