Nearly two centuries divide them. But Houghton Hall and Henry Moore are two of England’s national treasures. The former was built in the 1720s by prominent Georgian architects Colen Campbell and James Gibbs for Great Britain’s first Prime Minister, Sir Robert Walpole; the latter is considered the U.K.’s greatest sculptor of the 20th century—and the two have been brought together this summer for all to enjoy. “Henry Moore at Houghton Hall: Nature and Inspiration” displays six of Moore’s monumental outdoor works across the estate’s 4,000 acres. The artist is perhaps best known for his large figurative and abstract bronzes, but he also worked in fiberglass, and two such pieces, The Arch and Large Reclining Figure, appear on the verdant grounds. His smaller sculptures as well as models and etchings are on view inside the house’s ground-floor galleries.
