Settle back into your seat, the lights fade, and the whole ceiling above you comes alive — stars, galaxies, a rocket climbing away from Earth, the surface of Mars rushing past. That's the Digital Theatre at Armagh, a full-dome cinema where the film doesn't sit on a screen in front of you but curves right around your head, so you feel less like you're watching space and more like you're floating through it. It's the star turn here, and children come out of it wide-eyed.
Around the show there's a whole afternoon to fill. The exhibition floors are hands-on — buttons to press, models to work, corners built to explain gravity and light and how the planets move without a single dull display board. Then you head outside to the Astropark, a landscaped stretch of the grounds laid out as a scale model of the solar system: you literally walk the planets, from the Sun down the path to the outer worlds, past sundials, a stone calendar and a mechanical model of the heavens turning.
One thing worth knowing before you set off — the dome shows run to a set timetable, and pre-booking is essential, so it pays to check the show times and grab your slot ahead of the day. Do that and you've got one of Northern Ireland's most wonder-filled days: a proper journey to the stars and back, then a walk among the planets, all in the one place.
Plan your visit
Book your dome show — and check the show times
The dome films are the heart of the day and they run to a timetable that changes with the season — hourly at weekends and on Bank Holiday Mondays, and fewer during Northern Ireland school term time. The site itself says pre-booking is essential, so pick your show and reserve your slot before you travel rather than chancing it at the door. It's open Tuesday to Sunday plus Bank Holiday Mondays, 10am–5pm, last entry 4:30pm — closed on Mondays, so don't set out on one.

Getting there
College Hill, Armagh, County Armagh, BT61 9DB — just up from the centre of Armagh city, with free parking on site.
The Observatory at Armagh was founded in 1790 and is one of the oldest observatories still working anywhere in the world — a place where astronomers have been watching the sky for well over two centuries. In time the site grew into the Observatory and Planetarium you can visit today, pairing that long history of real science with a public home for the wonder of space.
The planetarium adds the modern magic: a full-dome Digital Theatre, hands-on exhibitions, and the Astropark spread across the grounds, where the whole solar system is shrunk to a walkable scale. It's a rare thing — a place that has genuinely helped map the heavens, opening its gates so families can go and feel that same pull of the stars for themselves.
