Dover Western Heights -Under Citadel Prison

⚠️ DISCLAIMER – DO NOT attempt to explore the location in this video ⚠️ Urban exploration is extremely dangerous. Your actions may result in serious injury or death. We have been exploring for many years and know how to handle extreme situations, but this is NOT something to copy. ⸻ In this special video we’ve combined two chapters of Dover’s hidden history: 1️⃣ The first half shows when we first discovered tunnelling in progress beneath the Dover Citadel – part of the vast Western Heights defences dating back to the Napoleonic Wars. 2️⃣ The second half documents our return, after the tunnel had been fully completed, leading into the long-sealed casemates deep inside the Citadel. These defences have been closed since the late 1960s, when the site was used by HMP Dover (later Dover Immigration Removal Centre). For decades, the casemates were completely cut off – until a small group of determined urban explorers spent five years carefully digging their way through. We didn’t dig this tunnel. That credit belongs to the explorers who revealed it inch by inch. 🔗 Stay Connected: IKS Archive: iksexploration.blogspot.com Instagram: instagram.com/iks_chris IKS Facebook Group: facebook.com/groups/iksproduction Email: [email protected] (for business inquiries) 🎥 Watch Next: 🔹 HMS WILDFIRE GILLINGHAM →    • HMS WILDFIRE GILLINGHAM   🔹 Explore Russian Submarine →    • Lets Explore U-475 Black Widow - Russian S...   ✨ Support the Channel: Buy me a coffee: https://buymeacoffee.com/iks_exploration Patreon:   / iks_exploration   YT Membership:   / @iks-exploration   🎵 Music & Credits: youtube music library 📜 Disclaimer: This video is for entertainment/educational purposes only.
