I picked up this great postcard recently, showing College Green in the snow with King Billy overlook proceedings.
The King William of Orange statue on College Green was eventually removed in 1929, following an explosion in the early hours of Armistice Day that year, but was one of the most vandalised monuments in Dublin prior to that. It sits right opposite the old Irish Parliament building. Inside the building, a tapestry showing the victorious King Billy at the Battle of the Boyne has outlived the monument, and you can still go and see it to this day by just walking into the bank. It was one of the stops on our recent walking tours of the city.
