The collection at the museum, which is perched atop Parnell Square North, will permanently house newer pieces.
Neil Jordan, a writer and director, has donated recently.
Visitors will be able to visit the more recent pieces among other noteworthy donations that date back to 1908 and this year.
One of the most notable recent additions to the gallery's collection is "Wall Landline Moor," a painting that was donated by the well-known artist Sean Scully.
It complements the exhibition of Richard Gorman's "Untitled," a collection of expansive pieces of custom-made Koso Washi Japanese paper provided by Neil Jordan and Robert Maharry.
Sacred trust: Donations and their Legacy is a stunning new exhibition which celebrates our Legacy of Donations, featuring significant gifts from 1908 to 2024.
