Dublin City Hall

Built in the late 18th century, Dublin City Hall is a classic Georgian building that was designed by renowned architect Thomas Cooley. Originally intended as the Royal Exchange for prosperous Dublin's large merchant population, inside it's all fluted columns and grand pillars, and as you enter you'll notice the beautiful rotunda. 
Then head to the vaults to visit the "Dublin City Hall, The Story of the Capital," exhibition. Through multimedia displays you'll get to trace the story of Dublin from Viking times before the Anglo-Norman invasion back in 1170, through to tales of the buzzing Irish capital today. 
Downstairs in the gallery, Dublin City Hall is also home to Tir na nÓg Caife, which serves breakfast, brunch, lunch, and snacks.
