Surfing the web for various inspirational reconstructions, like the Pudding Lane Productions one for London just before the Great Fire (and here’s another one from the same project, but at night), I came across this one for Tutbury Castle in Staffordshire:
Although I can’t vouch for the accuracy of this reconstruction, I rather like how it shows how the castle must have been a mix of its medieval origin and later accretions. Too often fantasy settings look like they’ve sprung from the earth fully-formed (ironically, representations of Tolkien’s Middle Earth are especially guilty of this, despite the setting’s detailed history, or perhaps because Tolkien himself was a great philologist but his sense of history was very flat). But RL is much more complicated, with old things always far outnumbering the new and providing the foundations, often literally, for it.
