Even on a tight schedule, GPO Witness History / O'Connell Street earns the hours.
Allow 1–1.5 hours.
The bullet-pocked columns of the still-working GPO and the slick 'Witness History' exhibition put you right at the heart of the Rising's drama. The honest catch: O'Connell Street itself is a tired, traffic-heavy boulevard that disappoints visitors expecting a grand avenue, and the paid exhibition is optional next to the free, free-to-see facade.
