A large Irish Free State force takes Drogheda, County Louth, on July 4, 1922, during the Irish Civil War. They defeat Anti-Treaty fighters who are based at Millmount Fort, a large, fortified complex situated on a great mound on the south bank of the River Boyne.

Millmount has been fortified in historical times since the early 12th century when invading Normans built a mote and bailey on what was probably originally a neolithic passage grave similar to Newgrange. In Irish cosmology, it is often assumed to be the burial place of Amergin Glúingel, whose name indicates that in ancient Irish mythology he was regarded as the originator of the arts of song, poetry and music.

Hugh de Lacy, one of the Normans who comes to Ireland after Strongbow, builds the original fort circa 1172, having been granted the Kingdom of Meath by Henry II of England. Later a stone castle is built on the site. This castle forms part of the defences of the town during the Siege of Drogheda during the Cromwellian conquest of Ireland in 1649. The fort’s English defenders attempt to surrender to Parliamentarian troops under Oliver Cromwell but are massacred when they give themselves up on September 11, 1649. The complex is later called Richmond Barracks. Some of the present buildings, in the courtyard, are built circa 1714. After the unrest and rebellions of the 1790s and the Acts of Union 1800 the complex is re-fortified, and the Martello tower is built.

The fort suffers considerable damage during the Irish Civil War. It is occupied by Anti-Treaty forces and on July 4, 1922, it becomes the target of shelling by the army of the Irish Free State. The Free State Forces under Michael Collins have been given extensive support by the British Army at the express wish of Winston Churchill who insists that the Republican Forces be crushed. Using the same British Army 18-pounder artillery piece which had shelled the Republican H.Q. in the Four Courts in Dublin some days earlier the Free State Forces bombard Millmount fort for several hours before the Republican garrison retreats. The famous Martello tower is all but destroyed during the shelling.

Today, after being restored in 2000, the complex houses the Millmount Museum which houses a wide variety of artifacts of local and national importance. The complex is Drogheda’s most dominant feature, clearly visible from all parts of the town. The Martello tower is affectionately known as “The Cup and Saucer” by locals. The whole fort is a national monument and has been designated as Drogheda’s Cultural Quarter.
