Mike Randolph is a writer, photographer and video producer based in Zaragoza, Spain. With over 20 years of experience, his work has taken him around the world and he has covered a wide variety of extreme sports and international sporting events. He is currently working on a multimedia project focusing on lesser-known aspects of Spanish culture.

In 2008, as a part of that project, Mike travelled to Tarragona, Spain, to capture still images of the Concurs de Castells, a biennial competition to see who can build the highest and most intricate human castles.

"It was one of the most riveting events I''d ever seen. And one of the most beautiful. It was the perfect real life metaphor for teamwork, families and friends of all ages pulling together to achieve something. It''s a triumph of Catalan culture. But I knew I had to go back and capture it on video. It''s just one of those events that''s made for video."

The sport of making Castells was recently recognised by UNESCO as being part of the Intangible Cultural Heritage of Humanity.

Casteller, filmed entirely on October 3, 2010, was directed, shot and edited by Mike Randolph. A selection of Mike''s work can be seen at www.randolphimages.com
