This drawing covers a section of the south coast bordering the Solent and Southampton Water. The defence requirements of this area were considerable as the Solent gave access to the important ports of Portsmouth and Southampton. Calshot Castle, shown here in red and black at the mouth of Southampton Water, was built by Henry VIII as part of a defensive chain defending the coast by cannon power. The drawing features a large decorative compass whose rays are visible extending to the edge of the land mass. Several corrections can be seen in black ink, where place names and the exact course of roads have been altered.
