The Dublin Festival of History starts today and continues until 9 October. There will be lectures, readings, screenings and walking tours on historical themes throughout Dublin City, with events taking place in Dublin Castle, City Hall, the IFI and Dublin City Council branch libraries.

In 1967, the National Museum of Ireland began an extensive excavation of the High Street area of Dublin, which lasted for three years. The work was filmed over this period by RTÉ for a special episode of the series 'Anthology', 'The Search for Viking Dublin.'

This TV clip shows scenes from the archaeological dig. Excavation director Breandán Ó Riordáin of the National Museum explains how they recruited staff from employment exchanges and the type of detective work involved in a dig like this.

'Anthology: The Search for Viking Dublin' was broadcast on 10 November 1969.
