About The Mansion House

The Mansion House is a house on Dawson Street in Dublin that has been the official residence of the Lord Mayor of Dublin since 1715; it was also the meeting place of Dáil Éireann from 1919 until 1922. It was commissioned by the merchant and property developer Joshua Dawson, designed in the Queen Anne style, built in brick with a stucco finish and completed in 1710. Dublin Corporation bought the house in 1715 as the Lord Mayor's residence.

What's inside

The house's best-known room is the Round Room, built in 1821 to receive King George IV. On 21 January 1919 the First Dáil assembled there to proclaim the Irish Declaration of Independence, and in 1921 the Anglo-Irish Treaty was ratified in the same room. The stained-glass window on the staircase was made by Joshua Clarke and Sons for Queen Victoria's visit in 1900. The symmetrical seven-bay front on Dawson Street has a central entrance framed by a pair of Ionic columns.
