Hudsons Bastion Dover.

Hudson's Bastion is a Napoleonic-era fortification on the eastern side of Dover Castle, built around 1793–1815 to defend against French invasion. Constructed to improve eastern defenses, it features firing slits, a caponier projecting into the dry ditch for flanking fire, and connecting tunnels to the main castle. #explore #kent #urbanexploration #Dover#historia #urbex #underground #history #abandoned #forgottenhistory
