The 186th tallest tower in the world
Rhymer's Tower, also known as Earlston Castle, is located near the village of Earlston, Scottish Borders, Scotland. The castle was the caput baroniae of the barony of Earlston. It was owned by the Lindsay family in the 12th century and passed to the Dunbar family in the 13th century. The ruins of a 16th-century border peel are all that remain.
