Dalkey - Eire 7

During the Second World War Ireland declared itself neutral, but its geographical proximity to England (especially Northern Ireland) made it exposed. Starting in September 1940, and until mid-May 1941, the German air force (Luftwaffe) carried out continuous heavy air raids against British cities what has been known as the Blitz. Around the same time, though on a smaller scale, the British air force (RAF) also began to carry out sporadic air raids against German cities. If German air raids lost strength from May 1941, British air raids increased from 1942 and onwards.

The technic used for navigation left a lot to be desired when bombers, regardless of nationality, tried find their targets and return safely back home. In darkness or bad weather, it was even harder to navigate correctly. Even in clear weather, it could be difficult to know where you were if the crew for whatever reason lost orientation.

Irish authorities wanted to minimise the risk of being mistaken for English territory and having foreign aircraft landing on Irish soil. Therefore, along the Irish coast, 83 large markings were established with the text Eire followed by a number. This would inform lost pilots that it was Ireland below them and nothing else. About ten kilometres southeast of Dublin lies the suburb of Dalkey and there along the coast is such a mark with the text Eire 7.
