Oh good, you've found one of our national historic sites, over two centuries old built when the British took it from the french, armeries, barracks, etc, also built overlooking as a strategic base. Not really a functioning wall to keep out immigrants, its full of boulengeries, petiseries, cafes, depaneurs, shopping etc. But hey, thanx for thinking of us.
Pretty creative with the pet names too eh, you know who else comes up with funny names for people?, children.
