The egg shed in Milltown is a small shed with a red door and a sloped roof, located in front of the housing estate at Millbrook. The egg shed was once used for sorting and storing eggs for collection by egg buyers from other regions. In April 1921, two RIC constables returning to their barracks after patrolling the railway station, were attacked by local volunteers at the egg shed. The ambush was carried out by ten to twelve local men to take the policemen's rifles and ammunition. However; it was not long before a number of armed policemen and Black and Tans rushed to the scene from the nearby police barracks and managed to retrieve the rifles.
