2. The Braveheart Heart

It is said to have been taken to the Holy Land during the 14th century, the heart of Robert the Bruce (d. 1329) was taken by his knights per his request. Robert the Bruce had vowed to go on a pilgrimage but, after realizing he would not live to make the trek, asked his friend Sir James Douglas to carry his heart in a silver casket to Jerusalem instead.

The embalmed heart of Robert the Bruce made its way into battle against Spanish Muslims (Douglas perished while in Spain), but never reached the Holy Land. It was taken back to Scotland and buried at Melrose Abbey.
