Where John Knox preached the sermon that helped ignite the Scottish Reformation — and later clashed face to face with Mary, Queen of Scots.
What happened here?
St Giles has been Edinburgh's principal church for centuries. Everything changed on 29 June 1559, when John Knox preached a sermon here that helped ignite the Scottish Reformation. Knox went on to become minister of St Giles', and the church was reorganised inside for Reformed worship: stained glass removed, old furnishings sold off, the interior later partitioned to hold three separate congregations at once.
Why does this matter to Mary's story?
Knox and Mary, Queen of Scots met face to face several times after her return to Scotland in 1561 — sharp, uncompromising exchanges Knox himself later recorded in his own history of the Reformation, between a Catholic queen and the man who had just helped end her church's authority here.
What happened next?
St Giles remained the centre of Reformed religious life in Edinburgh. Knox's statue now stands in the nave.
What to look for while you're here
- Knox's statue, standing in the nave where he once preached.
- The Thistle Chapel, added much later (1911) — a reminder of how the building has kept evolving.
- Traces of the building's Reformation-era reorganisation, still visible in its layout despite later restoration.
