This chapter feels like a further digression as we move back to describing the grounds themselves. Hugo reminds us that the convent was bounded by four separate roads and that there were high walls on all sides fully enclosing the grounds and those who lived within.
He notes that the garden itself that made up much of the middle was sunk lower and had a bit of a concave shape with a knoll at the very center. On this knoll there stood a solitary slender pine tree. Coming out from this knoll were four broad walks that comprised the shape of a cross. Between those walks lay 8 more smaller paths, a pair between each broad walk. This had the effect of creating a shape that resembled a wheel with a cross laid on top of it.
I don’t think I needed to know any of this. This entire section just feels pointlessly indulgent to me. Nevertheless we read on!
