Red Tower by sandysmith
Red tower marks the temination of the city walls - and once upon a time marked the beginning of an impassable swamp area.
The tower suffered from the battle ravages of the siege of 1644 and has undergone several restorations. The Tower was also formerly known as Brimstone House after a manufactory carried out within its walls.
