The Bank Buildings is a Grade B1-listed five-storey building located at the intersection of Castle Street and Royal Avenue in Belfast, Northern Ireland. It was designed and built between 1899 and 1900 by W. H. Lynn as a department store and warehouse, owned by the firm of Robertson, Ledlie, Ferguson & Co. It stands on the site of a bank erected in 1785, from which it takes its name. Since 1979, it has been owned by the Dublin-based company Primark, and serves as their flagship store in Northern Ireland.
