Trinity College Old Library and the Book of Kells

Step inside the 18th-century Old Library at Trinity College Dublin to encounter one of the world's most storied collections of human knowledge, anchored by the hypnotic artistry of the 9th-century Book of Kells.

What to expect — what visitors actually see/do

The experience begins in the Treasury, a dimly lit exhibition space where the Book of Kells—an illuminated gospel manuscript—is displayed. Visitors walk past glass cases containing intricate pages of Celtic knotwork and zoomorphic illustrations. Because the manuscript is so fragile, only two volumes are displayed at a time: one open to a major decorated page, the other to a text passage.

Exiting the Treasury, you ascend to the Long Room, a breath-taking, barrel-vaulted chamber stretching 65 meters. The air smells of aging calfskin and oak. You are flanked by two stories of floor-to-ceiling mahogany shelving holding over 200,000 of the library’s oldest texts. Marble busts of great philosophers and writers line the walkway, while the "Gaia" art installation—a massive, illuminated globe—often provides a surreal, glowing counterpoint to the centuries-old architecture.

History & significance — brief background

The Book of Kells was crafted by Columban monks around 800 AD; it is widely considered Ireland’s greatest cultural treasure for its elaborate calligraphy and early Christian iconography. The Long Room, completed in 1732, is the architectural heart of Trinity College. Originally, the room had a flat ceiling; the current barrel-vaulted roof was added in 1860 to accommodate the growing collection. It holds one of the few remaining copies of the 1916 Proclamation of the Irish Republic and the oldest harp in Ireland, dating to the 15th century.

Practical tips — opening hours, tickets, queues, best time of day

• Tickets: Booking online well in advance is mandatory. The attraction operates on timed-entry slots, and walk-ins are rarely accommodated during peak season.
• Best Time: Aim for the very first slot of the day (usually 9:00 or 9:30 AM) to experience the Long Room before the peak-afternoon tour groups arrive.
• Queues: Even with a timed ticket, you may queue outside on College Green. Expect to spend about 60–90 minutes inside in total.
• Photography: No flash photography is permitted inside the Treasury, as the light damages the ancient pigments.

Getting there — neighbourhood, transport

The library is located in the heart of Dublin 2 on College Green. It is a five-minute walk from the Trinity Luas (tram) Stop on the Green Line. Countless Dublin Bus routes stop directly outside the front gates on Dame Street. If arriving from the north side of the Liffey, cross O’Connell Bridge and head south onto Westmoreland Street; the college gates will be on your left.
