Henry Moore's reclining figure outside the Art Gallery of NSW in Sydney, Australia, has become a meeting point for adults and crawling point for toddlers. But it's just a tiny taste of Moore's magnificence. Visit his Perry Green estate in Hertfordshire to see what made him one of the world's most prolific contemporary artists. Stroll cow-green paddocks to trace the evolution of his reclining figure obsession. Pull-up in one of his studios, teetering with tiny plaster models of giant bronzes and his sketchbooks. Moore said: "All art should have a certain mystery and should make demands on the spectators." Let it resonate.
