Church Bastion was originally named King James’ bulwark in honour of James I but was renamed during the siege because of its proximity to the Cathedral. The 2 cannon on this bastion date from 1942 and were commissioned by Marchant Taylers London. This Bastian over looks the fountain estate and houses were built right against the walls from 1830 -1970. It now offers good views over the Fountain and over to the other side of the Foyle. The Fountain got its name from the reservoir that was built right next to this bastion in 1810.
