The ordnance survey is a large-scale government map, broken up into numerous sheets. The map displays the locations of all the streets, buildings, gardens, lanes, barracks, hospitals, churches and more throughout Dublin City. You can even see illustrations of the trees in St Steven’s Green. The rich detail gives you a clear idea of what Dublin looked like in 1847. You can see the contrast between the densely populated working class areas and the spacious wealthy homes of the upper classes. Many buildings have changed purpose or have been demolished completely over the last 100 years. For example, the Royal Dublin Society House is now Leinster House, the seat of Oireachtas Eireann.
Due to the famine, Ireland in 1847 was experiencing a dramatic change to its population. Hundreds fled to the city looking for work or poor relief. At the same time, the docks were filled with thousands emigrating out of the country to find a better life. The country was under British rule, which is evident by the names of buildings and roads. For example, after independence, Great Brunswick Street became Pearse Street. Some street names give a clear indication of what was located or happened in that area, such as New Church Street or Hospital Lane, but others could be taken as a warning such as Murdering Lane (sheet 19) next to Bow Bridge.
