St Patrick’s Tower is Europe’s tallest smock windmill (with a revolving top). It was built in 1757 to power the Roe Distillery, which by 1887 covered 17 acres and produced more than two million gallons of whiskey annually, making it Europe’s largest distillery. By the mid-1920s, however, the global whiskey market was in decline and the distillery was eventually sold in 1949 to its neighbours, Guinness. Today the tower is a feature of The Digital Hub, an tech and media enterprise cluster.
You can enjoy the sunshine in the seating area in front of the Tower. Sadly its not currently accessible.
