The National Library of Wales is home to the story of Wales. Perched on the hillside overlooking Cardigan Bay in Aberystwyth, it is one of the nation's most important cultural institutions, safeguarding Wales’s heritage for future generations.

The Library cares for an extraordinary collection of around 8 million books and periodicals, 30,000 manuscripts, 1.5 million maps, more than a million photographs and 70,000 works of art. It is also home to the National Screen and Sound Archive of Wales and Wales Broadcast Archive, which preserves film, video and audio recordings that capture the voices, stories and experiences of the people of Wales.

As one of the UK’s six legal deposit libraries, it is entitled to receive a copy of every publication produced in Britain and Ireland, ensuring that the nation's published memory is preserved.

Alongside preserving the past, the Library is committed to creating a sustainable future. Home to Wales’s largest EV charging hub, with 40 charging points, the site has also invested in air and ground source heat pumps, 1,622 solar panels and intelligent energy management systems to improve efficiency and reduce carbon emissions. Through its Climate Action Programme and award-winning sustainability work, the Library aims to become carbon neutral by 2028 while continuing to protect, preserve and share Wales’s heritage with the world.
