Carry on up Kildare Street and at St Stephen's Green take a right and then a right again down into Dawson Street. On your right Mansion House, official residence of the Lord Mayor of Dublin, is seen. A palatial building with the Dublin coat-of-arms on display and frequently used for official functions.
Walking on you cross the road at the bottom of Dawson Street and then bear left, following the footpath right past Trinity College, finally taking a right into College Street. There you have to cross the street opposite D'Olier Street. Admire the gothic Pearse Street Garda Station to your right, the romantic D'Olier-Building in front and the charming bronze sculpture showing the way to the "Screen" cinema in-between. Walk down Hawkins Street towards the Liffey, passing the faux-Tudor building of the Dublin Gasworks on your left. At the end of the street you will find a nice memorial to a policeman who died saving the lives of Victorian workmen trapped underground.
You are now at Burgh Quay and will have to bear right to walk downstream along the Liffey. Do not worry if the Liffey seems to flow in the opposite direction, this will be just a strong tide coming in. After a short walk you will have a splendid view of the faithfully restored Custom House on the north bank of the river. Cross over to the Northside using the modern Talbot Memorial Bridge and you will see the International Financial Services Centre on your right, dwarfing the moving Famine Memorial just beside the river.
