On 11 of July 1995 more then 8000 men were killed in Srebrenica. It is the single biggest massacre in Europe since WWII. And it happened in our backyard, not more then 10 hours of driving from Brussels.
We arrived on July the 10th. Unknowing that the yearly memorial day was one day later.
It made a huge impression on me and I believe it is one of the places every European should go to. It is our very recent history and it is a horrible one.
