In the 1970s, several buildings were demolished to make way for the construction of the Central Bank and its plaza. According to a document titled "Record of Protected Structures Former Central Bank etc Dame Street" from Dublin City Council, the Commercial Buildings (1799) were demolished in 1973 for this purpose. The new 'Commercial Buildings' was relocated on the site. The Central Plaza, also known as the Central Bank of Ireland Building, is an office building located on Dame Street in Temple Bar, Dublin. It's important to note that the demolition and construction efforts were part of urban development during that era, and the Central Bank building has since become a significant landmark in the area. For more detailed historical context, you can refer to the document on the Dublin City Council website.
