The Science Museum’s second-floor clock gallery tells the history of timekeeping through objects that enabled sailors to navigate at sea. London was the centre of clockmaking from the 17th to the 19th century. The gallery displays a clock that won the prize for measuring longitude, a problem that had caused shipwrecks and lost cargo. The gallery is located on the second floor, away from the crowded Space section on the ground floor.
Treasures Gallery at the Natural History Museum
The Natural History Museum’s Treasures Gallery is reached by stairs near the Darwin statue. The room holds a cabinet of curiosities, including a Barbary lion skull excavated from the Tower of London. The lion was part of the royal menagerie 700 years ago. The species is now extinct. The gallery also displays minerals, including a large topaz and a Victorian amethyst that its owner tried to discard.

Paintings galleries at the Victoria and Albert Museum
The Victoria and Albert Museum’s paintings galleries are on the second floor, accessed through the Silver Gallery. The Sheepshanks Collection includes works by William Blake and Edwin Landseer. The Ionides Gallery displays a shipwreck painting by Eugène Delacroix and a portrait by GF Watts. A separate room holds John Constable’s The Hay Wain alongside works by J.M.W. Turner. The galleries also display 15th-century Flemish tapestries once owned by the Dukes of Devonshire.
Pastels collection at the National Gallery
The National Gallery’s Room 42 holds a collection of pastel works that visitors often miss. The room includes Rosalba Carriera’s Portrait of a Man and Jean-Étienne Liotard’s Lavergne Family Breakfast. Pastels became popular in the 18th century for their soft finish and again in the 19th century with the Impressionists. The gallery displays pastel sketches by Edgar Degas.
National Portrait Gallery’s Tudor self-portrait
The National Portrait Gallery displays a 16th-century self-portrait by Gerlach Flicke, a German painter imprisoned in the Tower of London. Flicke painted the work using a mirror and included a portrait of his fellow inmate, the pirate Henry Strangwich. The portrait is believed to be the first self-portrait in oils created in Britain. The gallery also holds a decoupage screen made for Lord Byron by his boxing coach.
