Church Bastion, Derry City Walls (Images)
LDY014:033
It was from Church Bastion that King James II was fired upon as he approached the city on April 18th 1689, when the siege began in earnest. In the bastion you can see two demi-culverin cannon. Along the outer wall face is a small gateway, known as a ‘sallyport’. Tradition has it that this gateway was used during the siege, and that it leads into St Columb’s Cathedral.
