Millmount is a large fortified complex situated on a great mound on the South bank of the River Boyne located in Drogheda, County Louth, Ireland.

The fort has played a crucial part in Drogheda's history and has been a dominant feature from Norman settlement, to Cromwell's invasion to the more recent Civil War in 1922, in which the famous Martello tower was shelled and all but destroyed.

It has been fortified in historical times since the early 12th Century CE when the invading Normans built a motte and bailey on what was probably originally a neolithic passage grave similar to Newgrange.

[1] Hugh De Lacy, one of the Normans who came to Ireland after Strongbow, built the original fort circa 1172, having been granted the Kingdom of Meath by Henry II.

in the Four Courts in Dublin some days earlier the Free State Forces bombarded Millmount fort for several hours before the Republican garrison retreated.
