Ruined Castles of Mid-Lothian [PDF ebook] 
Their Position; Their Families; Their Ruins; And Their History

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Materials do not exist for an extended account of C’ousland Castle. The description of it, there fore, is necessarily brief. Though comparatively unknown, the Castle is a place of considerable interest, being closely associated with the sad tale of the unfortunate Mary Queen of Scots. It was under its shadow, and not on Carberry Hill, that her actual surrender, to the Associate Lords, took place on the 15th of June 1567.
