Dear Alma, Union Street still exsists & is off North Street & runs into Donegall St. where St. Annes Cathedral is. Berry St. runs off Royal Ave which goes onto North St. There is a College Sq. & College Sq. North There is also an Exchange St. near St. Annes Cathedral but I don't know about an Exchange building. All these streets are in close proximity to one another & quite near Smithfield Market. They are all in the city centre.I am getting this information from Collins Road Map of Ireland page 40.
