The expedition then moved on to Kalabsha, where Bonomi laboured to produce
Conservation and restoration of archaeological sites in order to add new materials. It is deemed justifiable if it is the only form of effective conservation available. or if conservation measures prove to be unfeasible.

This should only take place if the site would be heavily damaged or even eliminated if it were to not be moved. A famous example of this is the move of the Abu Simbel temples. The movement of these temples was expensive as well as challenging, but if the move did
