The celestial entrance known as 'Heaven's Gate' is located within the breathtaking Tianmen Mountain in China.

Situated approximately 5,000 feet above sea level, Tianmen Cave in China is the world's highest naturally formed arch.

Accessing this remarkable landmark involves ascending 999 steps, referred to as the "stairway to heaven," where the number nine holds significant meaning in Chinese numerology, symbolising good fortune and eternity.

Alternatively, visitors can opt for a bus ride along a narrow roadway. With dimensions reaching about 430 feet in height and 190 feet in width, the cave was once an ordinary cavern.

However, in 263 A.D., a section of the mountain's cliff collapsed, giving rise to the captivating appearance of a "portal to heaven" that mesmerizes observers to this day.
