The oldest building in Edinburgh is 16 feet long. 🏰
Sixteen feet.
You could park two cars in it.
It sits inside Edinburgh Castle — one of the most visited attractions in Scotland — and thousands of people walk past it every single day without going in.
I need you to go in.
This is St Margaret’s Chapel.
Built around 1130. The oldest surviving building in Edinburgh. A private royal chapel, built by King David I in honour of his mother.
His mother.
Queen Margaret was an English princess who fled to Scotland after the Norman conquest of England in 1066. She married the Scottish king Malcolm III and spent her life here — performing acts of charity, reforming the church, leaving something gentle on a country that was anything but gentle.
She died at Edinburgh Castle in 1093. Three days after hearing her husband had been killed in battle.
Three days.
Her son David became king. And he built this chapel for her. In her name. On the rock where she died.
In 1314, Robert the Bruce captured Edinburgh Castle and ordered almost every building destroyed.
Every building except this one.
He left the chapel standing.
And then, on his deathbed in 1329, Robert the Bruce remembered Queen Margaret. He ordered the chapel repaired. He set aside money for it personally.
A dying king. His last thoughts including a small chapel built for a woman who had been dead for 236 years.
And then.
In the 1500s, with the Reformation sweeping through Scotland, the chapel fell out of use.
And Scotland — this beautiful, dramatic, absolutely chaotic country —
Used it as a gunpowder store.
A chapel built by a king for his sainted mother.
Survived by Robert the Bruce.
Repaired on a dying king’s orders.
Used to store gunpowder.
Its origins completely forgotten.
Just a convenient stone room. Full of explosives.
In 1845, an antiquary named Sir Daniel Wilson looked at this small room and realised what it actually was.
He had it restored.
Today it is cared for by the St Margaret’s Chapel Guild — a group of women named Margaret, who maintain it, provide the flowers, and keep it exactly as it should be.
A guild of Margarets. Looking after a chapel built for a Margaret.
Scotland. Never not extraordinary.
It still hosts weddings and christenings today.
In a room the size of two parked cars.
Built in 1130.
That has survived everything.
Go inside. Stand in it. Put your hand on the stone arch.
That arch is original. Those stones are from 1130. The same stones Margaret’s son ran his hands over when he built it for her.
You are touching the same thing.
Almost 900 years apart.
Scotland does this to you. If you let it. 🏴
