The Spanish Arch is a remnant of Galway's medieval city walls, built in the 16th century to protect the harbor. It was part of the city's fortifications and got its name from Spanish ships that docked here to trade wine. Located beside the River Corrib and the city museum, it stands today as a symbol of Galway's maritime and trading heritage. The surrounding area features cafes and restaurants with wonderful views of the river and the old quay, making it a popular gathering spot.
