This Georgian-style civic building with a rotunda offers a multi-media exhibition, tours and lectures. City Hall was built between 1769 and 1779. The build took ten years to complete. When they decided to build City Hall a competition was advertised and 62 submissions were made. The winner of this Competition was Thomas Cooley, a young architect from London. At the time, James Gandon would have been the primary architect in Dublin, but his designs came second in the competition. Thomas Cooley was also tendered to build the Four Courts, however at 44 years of age, he fell ill and died and therefore James Gandon became the primary architect in the building of the Four Courts.
