In 2019, British photographer Christopher Wilton-Steer traveled 40,000 kilometers along the old Silk Road from London to Beijing.

Over four months and 16 countries, Wilton-Steer travelled by car, bus, train, ferry, horse and camel. That journey is now the basis of an outdoor photography exhibition presented by The Aga Khan Foundation, The Silk Road: A Living History, at Granary Square in London's King's Cross.

The Silk Road refers to a network of ancient land trade routes linking Asia and Europe.

The exhibition, which runs until June 16, comprises more than 160 photographs, showcasing the diversity and culture along the Silk Road in countries such as Iran, Turkmenistan, Uzbekistan, Tajikistan, Kyrgyzstan, Pakistan, India and China.

"From a young age the idea of the Silk Road, merchants and travelers journeying hundreds or thousands of miles into unchartered territory and discovering new worlds, captured my imagination," Wilton-Steer said. "I became fascinated by the Middle East, Central Asia and China, and read lots about these places."
