Trinity College Library 🇮🇪

The Library of Trinity College Dublin is the largest library in Ireland and serves as the university's main repository system. Established alongside the founding of Trinity College in 1592, it operates as a legal deposit institution entitled to copies of all works published in the Republic of Ireland, while also maintaining rights to receive requested materials published throughout the United Kingdom.

The central highlight for visitors is the Old Library, designed by Thomas Burgh and constructed between 1712 and 1732. Built using fossil-bearing Calp limestone quarried in Palmerstown along with granite, this landmark structure offers an imposing view of the university grounds from Nassau Street. Inside, the prominent Long Room spans 65 metres and contains roughly 200,000 of the library's oldest texts. Originally designed with a flat ceiling, the Long Room had its roof elevated in 1860 to accommodate an upper gallery for extra shelving.

A lined row of marble busts depicting notable writers, philosophers, and university benefactors accents the Long Room. Key pieces include a portrait bust of Jonathan Swift by sculptor Louis François Roubiliac, alongside recently added sculptures honoring historical female scholars. The hall also houses major historic artifacts, such as a preserved copy of the 1916 Proclamation of the Irish Republic and the 15th-century Brian Boru harp, an Irish national icon constructed from oak and willow with 29 brass strings.

The library is world-renowned for its treasury of ancient manuscripts, anchored by the Book of Kells. Given to the institution in 1661, this 8th-century text is showcased in a display system that permits various pages to be viewed publicly. Additional rare works in the holdings include the Book of Durrow, the Garland of Howth, and thousands of early printed volumes bequeathed by 17th-century Archbishop James Ussher.

In addition to its original quarters, the library encompasses multiple modern facilities across the campus and beyond. Key campus sites include the Brutalist Eavan Boland Library, the Lecky Library, the James Ussher Library housing the 24-hour Kinsella Hall study space, and the 1937 Reading Room reserved for postgraduate study. Specialized departments include the Glucksman Map Library, the Hamilton Science and Engineering Library, and supplementary off-site storage in Santry and affiliated medical centers.
