Tour Scotland video of Smailholm Tower on a visit to the Scottish Borders. This Scottish peel tower is located five miles West of Kelso on a crag on top of Lady Hill. It was originally built in the 15th century or early 16th century by the Pringle family. The tower was attacked by English soldiers in 1543, 1544 and again in 1546, when the garrison of Wark Castle sacked the tower and carried off prisoners and cattle. The castle was successfully defended against the English in 1640, by Sir Andrew Ker of Greenhead.
