Couples in Germany attach locks like this to bridge rails – as a token for their indivisible love. I do not know who put this lock at a fence in the Old City of Jerusalem. But “Custom creates law” becomes highly political in a land which three world religions and two nations claim as their own. Monks in the Church of the Holy Sepulchre use it to enlarge their church space and Israeli Settlers are building whole cities in the West Bank hoping that this principle holds true. This lock was put there to divide.
