The eight hundred year-old heart of St Laurence O'Toole has been returned to Christ Church Cathedral in Dublin, six years after it was stolen.

His heart is one of many relics across Ireland in churches, another notable one being the head of Saint Oliver Plunkett in St Peter's Church in Drogheda.

Historian Dr Niamh Wycherley, from the NUI in Galway, explains why we have such relics in our churches and if they still have the same significance as they did hundreds of years ago.
