Historical Information about Stirling Castle (from Wikipedia):
Stirling Castle, located in Stirling, is one of the largest and most important castles, both historically and architecturally, in Scotland. The castle sits atop Castle Hill, an intrusive crag, which forms part of the Stirling Sill geological formation. It is surrounded on three sides by steep cliffs, giving it a strong defensive position. Its strategic location, guarding what was, until the 1890s, the farthest downstream crossing of the River Forth, has made it an important fortification from the earliest times. Most of the principal buildings of the castle date from the fifteenth and sixteenth centuries. A few structures of the fourteenth century remain, while the outer defences fronting the town date from the early eighteenth century. Several Scottish Kings and Queens have been crowned at Stirling, including Mary, Queen of Scots, in 1542. There have been at least eight sieges of Stirling Castle, including several during the Wars of Scottish Independence, with the last being in 1746, when Bonnie Prince Charlie unsuccessfully tried to take the castle. Stirling Castle is a Scheduled Ancient Monument, and is now a tourist attraction managed by Historic Scotland.
The first record of Stirling Castle dates from around 1110, when King Alexander I dedicated a chapel here. It appears to have been an established royal centre by this time, as Alexander died here in 1124. During the reign of his successor David I, Stirling became a royal burgh, and the castle an important administration centre.[9] King William I formed a deer park to the south-west of the castle, but after his capture by the English in 1174 he was forced to surrender several castles, including Stirling and Edinburgh, under the Treaty of Falaise. There is no evidence that the English actually occupied the castle, and it was formally handed back by Richard I of England in 1189. Stirling continued to be a favoured royal residence, with William himself dying there in 1214, and Alexander III laying out the New Park, for deer hunting, in the 1260s.Historical Information about the Keeper of a Castle (from: http://thelawdictionary.org/constable-of-a-castle/)
