In 2016 I visited Krakow (Poland) with my girlfriend, with the main purpose of visiting the former German Nazi Concentration and Extermination Camp Auschwitz-Birkenau. This was a visit that we will never forget. It was so unrealistic to walk there and know how many people died there. Of course I have taken a number of photos there, with the utmost discretion, that I wanted to publish today on May 4 Remembrance Day.
