with Galway, the Spanish Arch stands on the left bank of the Corrib, where Galway's river meets the sea. The arch is the remainder of a 16th century bastion, added to the town's walls to protect merchant ships from looting. At this time, it was known as Ceann an Bhalla (Head of the Wall).
Its current title Spanish Arch dates from the last century - a reference to the former merchant trade with Spain, whose galleons often docked under its protection.
