I visited Kalwaria on Thursday and Friday of the Easter week in 2007 and followed Jesus for 10 hours over the two days. I was told that this was the largest annual Passion Play in Europe, with estimated 60,000 people following him. I assume most people were Polish and guarantee that I was the only Asian. It took 10 hours because at each of some 40 chapels some monks spoke in Polish, which I don't understand. I was trying to figure out what drives people to Christianity, but after 10 hours I was a devout Christian!
