Joseph's Tomb is one of the most sensitive religious sites around Nablus, traditionally associated with the biblical Joseph and revered in overlapping Jewish, Samaritan, Christian, and Muslim traditions. Its importance is real, but so is the political tension around access.
Treat this as a place to understand before you attempt to visit. Conditions can change quickly, and independent travellers should seek current local advice rather than assuming ordinary shrine access; for many visitors, seeing the area with a knowledgeable local guide is the only sensible approach.
