I worked for a number of shipping companies located on North Wall Quays back in the late 1960s and it was to be avoided especially at night but the area has completely changed and the rate of change is increasing week be week.
Dublin North Wall is the area east of the inner north side of Dublin, along the Liffey. It contains the entire north side of Dublin Docklands and includes the International Financial Services Centre, Spencer Dock, and further east the main part of Dublin Port.
The area is dominated by a combination of older buildings, dockland activities and new development through the Docklands Strategic Development Zone Planning Scheme, including extensive construction of new retail, residential and office spaces.
Below is a link to an excellent books that includes some of my photographs [without my photographs the book is still excellent].http://www.turtlebunbury.com/published/published_books/docklands/north_wall/pub_books_docklands_history_northwall.html
