The historical document, which was found in an airfield in Berlin, was used by the Luftwaffe to carry out the bombings of 1941.
Belfast was seen as something of a soft target during the World War Two - and the map shows just how serious the Germans were about causing maximum disruption.
"What happened is the Germans have added their own legend which shows the details of what areas are targets and they're all numbered along the side and you realise that these are marked as potential targets," said Ciaran Elizabeth Doran from the NI War Memorial.
"We've translated all of these, and even the area of the rope works was targeted - the reason being that they made camouflage nets so everything is designed with the most impact."
It is 72 years since the first German bombs fell on Northern Ireland during what would be known as the Belfast Blitz, which killed around 1,000 people and left 100,000 more homeless on the night of Easter Tuesday 1941.
The map will be on display at the NI War Memorial for the foreseeable future.
