I'm on vacation, there is a Catholic pilgrimage shrine in the town next to where I'm staying. Pilgrims get here by bus, they can borrow a wooden cross and circumambulate the chapel containing an icon of Mary. It's a fascinating mix of devotion, sacred space, commercialism, mass tourism, the mundane lives of the local population, and so on. Pilgrimage sites fascinate me because of these tensions and the visibly complex social fabric. What are your experiences with modern-day pilgrimage?
