Note 117 — Chapter VI · Remaining Events of 1643; and the First Siege of Lathom House.
Reading edition
Thurland Castle is still of much the same extent as formerly, but the old building only remains in the lower part of the walls. Two pictures in Philips' "Lancashire Halls," 1822-24, show a very dilapidated building. The moat is three or four yards wide and seven feet deep, and is still only crossed by a single bridge.
