King William added to the amenity of Stirling Castle by forming a royal park on the table-land to the south-west of the rock. In causing this enclosure to be made, he unwittingly trespassed on property belonging to the monks of Dunfermline, and the following deed of excambion shows the King’s acknowledgment of the mistake and his readiness to give compensation to the abbey: “Willelmus Rex Scottorum omnibus probis hominibus tocius terre sue, clericis laicis, salutem. Sciatis me concessisse et dedisse et hac carta me confirmasse Deo et ecclesie Sancte Trinitatis de Dunfermelyn et monachis ibidem Deo seruientibus et Capelle Castelli mei de Striuelin in excambium terre sue quam primum clausi in parco meo quando parcum meum primum clausi, terram que est inter terram suam quam habent extra parcum et diuisas terre de Kirketun et ex alia parte terram que est inter Cambusbarun terram Petri de Striuelin et terram Rogeri filii Odonis, sicut magna strata uadit ad Cuiltedouenald, sicut Ricardus de Moreuilla, constabularius, et Robertus Auenel, justiciarius, et Radulphus vicecomes, et Petrus de Striuelin perambulaverunt: Tenendam in perpetuam elemosinam ita libere et quiete, sicut alias elemosinas suas tenent: Testibus, Ricardo de Moruilla, constabulario, Roberto Auenel, justiciario, Alano filio dapiferi, Adamo filio Thome, Rogero de Voloniis, Radulpho vicecomite de Striuelin, Petro de Striuelin, Waltero de Berkelai; Ricardo clerico apud Striuelin.”[7] In English this runs as follows: “William King of Scots to all good men of his whole realm greeting. Know that I have granted and given and by this charter have confirmed to God and the Church of the Holy Trinity at Dunfermline and the monks there serving God and to the Chapel of my Castle of Stirling in exchange for their land which I formerly included in my park, when I first enclosed my park, the land which is between their land which they have outside the park and the boundary of the land of Kirkton, and on the other side the land which is between Cambusbarron--the land of Peter of Stirling--and the land of Roger, son of Odo, as the highway leads to Cuiltedouenald, as Richard Morville, the constable, Robert Avenel, the justiciar, Ralph the sheriff and Peter of Stirling have marked it out: to be held in perpetual alms. Witnessed by Richard de Morville, constable, Robert Avenel, justiciar, Alan, son of the Steward, Adam, son of Thomas, Roger de Voloniis, Ralph, Sheriff of Stirling, Peter of Stirling, Walter de Berkeley, Richard the clerk, At Stirling.”
