Dublin · Things to do

Guided tours only of the 1796 prison where the 1916 leaders were executed. €8 adult, €4 student, under-12s free but still ticketed; allow 90 minutes. Pre-booking online is essential and slots sell out — the visitor centre opens at 9am, the gaol from 10.30am.

Free, on Kildare Street, and the single best hour in the city: the bog bodies, the Ardagh Chalice and the Tara Brooch under one roof. Open Tue–Sat 10am–5pm and Sun–Mon 1pm–5pm, no booking needed.

The ninth-century manuscript and the Old Library on a timed-entry ticket. Buy only through visittrinity.ie — the college has warned about copycat resale sites. The campus squares themselves are free to walk through if that is all you want.

Seven floors at St James's Gate finishing in the Gravity Bar with an included pint and a view over the city. Book a timed slot online; this is Dublin's busiest paid attraction and the mid-afternoon queues are real.

The largest enclosed park in any European capital, 1.5 miles from O'Connell Street and open 24 hours; the wild fallow deer herd is usually out on the Fifteen Acres. Free, with a visitor centre, the Victorian flower gardens and Dublin Zoo inside. Side gates close around 10.45pm.
