Double Bastion, Derry City Walls (Images)
Double Bastion occupies the south-west corner of the layout of the walls and, following removal of surrounding nineteenth century housing in Nailor’s Row, is one of the most prominent parts of the Monument and the site of one of the best known cannon ‘Roaring Meg’. The bastion
is separated from the rampart walkway by a low stone plinth wall and, during the nineteenth century, was planted as a private garden.
