Walk the full length of the caves to the inner chamber

Cross the underground stream called the Styx

Climb to St Lawrence's church with its golden ball

Walk round the open hexagonal mausoleum on the hill

From 1748 Sir Francis Dashwood had a network of chalk and flint tunnels dug about a quarter of a mile into the hill above West Wycombe, giving work to villagers after failed harvests and a meeting place to the Hellfire Club. The caves run directly beneath St Lawrence's church and the hexagonal mausoleum he also built, and end at an underground chamber across a stream called the Styx.

The Hellfire Caves: Dashwood's Tunnels Under West Wycombe

Go underground at the Hellfire Caves in West Wycombe, dug in 1748–1752 for Sir Francis Dashwood, whose club became known as the Hellfire Club

Drive the scenic roads of the Chilterns between West Wycombe and Hughenden

The Hellfire Caves at West Wycombe were dug in 1748–52 for Sir Francis Dashwood, whose Order of the Friars of St Francis of Wycombe became known as the Hellfire Club, and on the hill above them the church tower carries a golden ball. Benjamin Disraeli lived at Hughenden Manor from 1848 to 1881, and in the Second World War it hid a secret map-making operation codenamed Hillside.

Across the Thames, Henry VI founded Eton College in 1440, and down the river at Runnymede King John sealed Magna Carta in 1215, where the memorial went up in 1957.

Warner Bros. built the Harry Potter films at Leavesden, on the site of Leavesden Aerodrome, a wartime de Havilland aircraft factory, and kept the sets when the shooting finished: the Great Hall, Diagon Alley, the Hogwarts Express on its platform, the Forbidden Forest and the 1:24 model of the castle that was filmed for the exteriors.

See the mosaics and hypocaust in Verulamium Park

Visit the shrine of St Alban in the cathedral

Verulamium grew into a major Roman town of some 125 acres, sacked by Boudica and rebuilt; Watling Street ran through it, and it had a forum, a basilica and a theatre whose remains are still visible, with mosaics from its houses in the museum. Above it, the abbey church was raised near the traditional site of the martyrdom of Alban, the first British martyr, with Roman bricks from the ruined town built into its tower.

Find the Iguanodon with its thumb spike on its nose

Walk the whole island circuit and count the extinct animals

See the Megalosaurus and compare it with what we know now

Walk the terraces of the old Crystal Palace site above the lake

Benjamin Waterhouse Hawkins built these life-sized models for the Crystal Palace park under the direction of Richard Owen, the anatomist who coined the word Dinosauria, and they were unveiled in 1854 — the first dinosaur sculptures in the world. They are wrong in ways that are now famous: the Iguanodon stands on four legs with its thumb spike on its nose. That is the point of them.

Look up at the House in the Clouds from the Meare

Row on the Meare, the shallow boating lake dug in 1913

See Thorpeness windmill that pumped the water up

Thorpeness was built as a mock-Tudor holiday village, and in 1923 its water tower was dressed up as a weatherboarded house so it would fit in — a 50,000-gallon tank hidden behind windows and gables, apparently floating above the trees. Anti-aircraft fire hit it by accident in the Second World War, and when mains water arrived in 1977 the tower became redundant; in 1979 the tank was taken out to make more rooms.
