For the cyclist, this is the main attraction. The café is located in the old armoury and is known for its hearty soups, homemade cakes, and good coffee. You could almost call it a cycling café.

Modern cable-stayed bridge from 2009, designed by Santiago Calatrava, recognizable by its large white arch and 31 cables that together evoke the shape of an Irish harp. The bridge connects Sir John Rogerson’s Quay to Guild Street in the Docklands and can rotate 90° to allow ships to pass. It is one of the most photogenic spots along the Liffey, especially in the evening light with the reflections on the water.

A beautiful sandy beach right in Dublin. It's busy, at least in the evenings, but not overcrowded.
