Underground Great Wall Exploration

Exploring Project 816: Touching the Burning Patriotic Sentiment

Stepping into Project 816 in Baitao Town, Fuling, Chongqing, feels like traveling through time to touch an eternal memory carved into the mountains and rivers. This "Underground Great Wall" hewn by faith has endured eighteen years of silent perseverance, where sixty thousand unnamed heroes hid their identities and forged their youth into the cornerstone of peace.

Purchase tickets online in advance for 65 yuan per person, including guided tours and sightseeing bus. After driving to the scenic area parking lot, you need to transfer to a shuttle bus to reach the project entrance. Inside the cave, the constant temperature of 18°C instantly takes you away from the outside heat, but it’s wise to bring a light jacket.

Follow the professional guide through a maze of over 130 tunnels, the main cave chamber 79.6 meters high, the pot bottom with 2,001 nuclear fuel slots, the restored central control room... every detail tells the story of the dedication and sacrifice of the Third Front construction workers. There is no smoke of war here, but it witnesses the most passionate patriotic sentiment.

When standing at the pot bottom and looking up at the steel bars crisscrossing like a spider web, you truly understand: the real "great national weapon" is never cold steel, but the youth silently burning in the hearts of millions.
