Concrete Fortification Wall Cross-section
The cut through the Battery Lancaster wall provides the view and circulation to the north, and also reveals a cross-section of a 15-foot-thick defensive wall, behind which a cannon was placed in 1898. By then, cannon fire from ships had become more powerful, making such defensive works necessary.
