Rory O'More Bridge (Irish: Droichead Ruaraí Uí Mhóra)[1] is a road bridge spanning the River Liffey in Dublin, Ireland and joining Watling Street (by the Guinness grounds) to Ellis Street and the north quays.

This tower was later relocated to the Royal Hospital, Kilmainham after traffic congestion increased with the arrival of the railway in 1847.

[4] Designed by George Halpin, the bridge was fabricated at the foundry of Robert Daglish in St Helens, Lancashire, from cast iron (with a wrought iron deck) and is supported on granite abutments.

[4] Both the upstream and the downstream sides of the bridge were transported by ship and brought up river to be manoeuvred into position at the site.

[5][6][7] The bridge was renamed in the 1930s for Rory O'More (1600–1655), one of the key figures from the plot to capture Dublin as part of the Irish Rebellion of 1641.
