It took 10 years to build the original – but it's unlikely to have as many pieces as this model.
A Lego version of Dublin's City Hall took 300,000 pieces and five months of patience to construct.
It has now found a permanent home in Ballyfermot Library having spent the past three-and-a-half years in storage.
Officials at the library said that the little known piece of art was commissioned in 1988 for the capital's millennium celebrations.
The Lego is displayed behind a glass panel in the library and was designed and built by Elaine Jones, of Lego UK.
The library said Ms Jones had full access to the original architectural drawings of the city hall building from its design in 1768.
She built the Lego design with an open back to allow people to look inside the hall building, which contains the original City Hall design inside.
The model was on display for the Dublin Be Proud exhibition in Arnotts shop in Dublin city centre from March 24 to April 9 in 1988.
