The Poolbeg Chimney Stacks, also known as the “Poolbeg Stacks,” are two large chimneys located in Dublin, Ireland. They were built in the 1970s as part of the Poolbeg Incinerator, a waste-to-energy power plant. The chimneys are approximately 250 meters tall and are a prominent feature of the Dublin skyline.

They are considered a local landmark and are visible from many parts of the city. The plant was closed in 2010, but the chimneys still stand. Due to popular demand, the chimneys have been kept as they are iconic feature of Dublin.
