St Peter's is the Catholic church on West Street, Drogheda's main street. It was completed in 1793, when Catholic worship was only just tolerated, and was greatly extended in the 1880s with a striking tower. Most visitors come for the shrine of Saint Oliver Plunkett, Archbishop of Armagh, who was condemned in a rigged trial and hanged, drawn and quartered at Tyburn in 1681. His preserved head has been on display here since 1921.
It is an odd and slightly macabre sight, but a moving one for many Irish Catholics. Don't confuse this church with St Peter's Church of Ireland a block north on Peter Street, where in 1649 Cromwell's soldiers set fire to the steeple with Royalist soldiers sheltering inside.
