The name of St Olav’s church in Waterford testifies to the city’s Viking origins: Olaf II was a Norweigan king killed at the Battle of Stiklestad in 1030, and canonised in 1164. The original church here, likely made of wood, is supposed to have been constructed around 1050, long before Olav became a saint, so it must have been named after him at a later date, perhaps when the stone structure was built. The latter had fallen into ruin by the early 17th century and only an arched doorcase survives at the west end of the present church, which occupies the same site but was erected in the 1730s on the instructions of the then-Bishop of Waterford, Thomas Milles: its design has been attributed to William Halfpenny who, during the same period, produced designs for the Bishop’s Palace and Christ Church Cathedral, neither of which were executed (see: The Finest 18th century Ecclesiastical Building in Ireland « The Irish Aesthete). St Olav’s remained a place of worship until 1970 and today serves as a community centre.
