Students have been "enlightened" with the opening of a refurbished library and community hub complete with a children's slide.
The Kevin Street Library, which has been closed for five years while undergoing €3.9m of refurbishments, has reopened, and local schools and community groups joined in the celebrations.
More than 100 people turned up to mark its new lease of life as musicians and a local children's choir performed for guests.
The modernised building includes a mezzanine and reading room as well was an animated children's area with the slide.
Pupils marked the opening by reading poems and stories they had written for guests.
"'Enlightened' is a good word to use because some of them have openly told us they haven't been in a library in the last couple of years," said Dermot Grier, a teacher at Presentation Secondary School Warrenmount.
"In reality, some of the students would have very little contact with their library and going to libraries, so it's about encouraging them that a lot of these resources are on their doorstep.
"It's warm, it's open, it's very user-friendly and there's a lot of resources here that the girls could use."
Dublin city librarian Brendan Teeling said there were more plans for the capital.
"We want our libraries to be places where community groups feel welcome and can make use of them for their own purposes, because people have a variety of interests that can be put to use here," he said.
"We want the library to be a place where they can indulge. We make them full of life and full of people.
"We have plans for a new library in Finglas, plans for a library a little bit further west of the city, and we're very committed to developing the library services further than that."
