King George I Square is the central civic and social hub of Patras, laid out in the mid-19th century as part of the city's post-independence grid plan.

Cafés and restaurants line its perimeter, making it a prime spot for people-watching. It remains the primary venue for public gatherings, demonstrations, and key events of the famous Patras Carnival, continuing its long tradition as the city's main stage.
