Nicola Pierce is the author of O'Connell Street: The History and Life of Dublin's O'Connell Street. It is a book as much about people as buildings, which charts the unique story of Ireland's most famous street. Now illuminated in a unique way as part of Dublin Winter Lights, we walked the street together on a busy evening chatting about its statues and landmarks.
