Martello Tower In Skerries, Red Island, Dublin, Ireland Royalty-Free Stock Photo

Since people thought that Napoleon might firstly try to take over Ireland, in 1804 the first tower forts appeared here. Most of them were built on the coast line and around the area of Dublin, including the island ‘Ireland’s Eye’ and ‘Lambey Island’. The British built about fifty Martello towers around the Irish coastline, especially along the east coast, from Millmount Drogheda, to Bray, around Dublin Bay but also around Cork Harbour on the south coast. On the east coast, concentrated mainly around Dublin Bay, twenty-six towers were in line of sight of each other, providing the ability to communicate with one another, or warn of any incoming attacks.
