Stunning - you can see it even from the castle entrance. Really appreciate the historical background provided in previous reviews.
The monument is fairly easy to spot due to its location on a hill, and because the white structure stands out among the gray headstones. Access to the cemetery should be open anytime of day or night and it is for free.
A lovely memorial to the Wilson sisters who were tried for treason and drowned due to them being covenanters, its set in the graveyard below the castle , there is an information board that tells their sad story and the subsequent building of the monument in 1859
