Dublin Before the Georgians
Medieval Dublin was a walled city built by the Vikings and expanded by the Normans. The traces of this earlier city survive beneath and alongside the more visible Georgian and Victorian layers — Christ Church Cathedral (founded by the Vikings in 1030), St Patrick’s Cathedral (built from 1220), Dublin Castle’s medieval undercroft, the city walls (sections visible at St Audoen’s Church), and the street pattern of the Liberties and Temple Bar, which follows the medieval layout.
A medieval Dublin tour connects these surviving fragments into a narrative of the city’s first 600 years — Viking settlement, Norman conquest, medieval trade, plague, and the gradual expansion beyond the walls.
