Her tomb is at the church of Brou in Burgundy:
The church of Brou which was begun in 1506, but which was completed by Margaret of Austria. Margaret was one of the ladies who brought about what was known as La Paix des Dames or the Treaty of Cambrai in 1529, when Queens brought about a Peace which Kings and Councils could not arrive at.
As a child, Margaret was a pawn in the game of statecraft. She was first betrothed to a king's son in France and sent to Paris to be educated in Court ways; but the old king died. Then she was sent to Spain to be betrothed to the Infante; and he died; and so she escaped that. At last she made a love match of her own with Philibert, the Duke of Savoy; and he was killed by a fall from his horse while hunting.
It was while on her voyage to Spain and when the ship which was carrying her thither came nearly being crushed on the rocks of the French Coast, that Margaret wrote an epitaph to be used for her resting place in case of need, humorously worded in order to amuse her terrified companions; and these were the lines:
"Ci-git Margot, la gentille demoiselle;
Qui eut trois maris, mais mourut pucelle"
When Philibert was killed Margaret built herself an oratory at Brou, and gave up her life to building its exquisite Church, the rood-screen of which is like a piece of lace in stone. Margaret was diverted from this task to become regent of the Netherlands and when she died there her gentlemen-in-waiting carried her body on their shoulders all the way in the snow to Brou.
