SITUATION.
Bolingbroke, a decayed market town, is distant about eight miles south east from Horncastle, and gives name to the soke wherein it is situated. The town is seated on a clear, rapid brook, from which the name is derived, and which runs along a peculiar deep recess of rugged sand-stone hills, which suddenly terminate at the northern border of the adjacent fen district. Embayed amid these deep declivities, and having but one narrow outlet into the level land, it is a matter of no surprize that its importance as a place of security was not overlooked in the feodal times, when it became further strengthened by a castle.
