Ireland developed a strong middle class, especially in the major cities, by the mid-nineteenth century. They were active patrons of department stores. Delany's New Mart was opened in 1853 in Dublin, Ireland. Unlike others, Delany's had not evolved gradually from a smaller shop on site. Thus it could claim to be the first purpose-built Department Store in the world. The word department store had not been invented at that time and thus it was called the "Monster House". The store was completely destroyed in the 1916 Easter Rising, but reopened in 1922.
