• One of the world’s most valuable watches – the No 160 watch which Abraham-Louis Breguet designed for Marie Antoinette but which wasn’t completed until the 1820s, well after her death – is the star of the show at the Science Museum’s new exhibition Versailles: Science and Splendour. Opening today, the exhibition, created in partnership with the Palace of Versailles, takes visitors on “a 120-year journey through the evolution of science at Versailles” and explores how Louis XIV, Louis XV and Louis XVI encouraged the pursuit of scientific knowledge and harnessed that knowledge as a tool of power. More than 100 objects are on display and, along with Breguet’s watch, they include Louis XV’s rhinoceros, a detailed map of the moon by Jean-Dominique Cassini, and Claude-Siméon Passemant’s Clock of the Creation of the World (1754). The watch, meanwhile, has its own fascinating history, including two decades in which its whereabouts were unknown after it was stolen in 1983 (in fact, its display in this exhibition marks the first time the timepiece has travelled abroad since its safe return to the LA Mayer Museum for Islamic Art in 2008). Runs until 21st April. Admission charge applies. For more, see sciencemuseum.org.uk/see-and-do/versailles.

• A medieval silk seal bag, which dates from the reign of King Henry III, has gone on public display for the first time in the Queen’s Diamond Jubilee Galleries at Westminster Abbey. The display follows the discovery by scholars that the bag’s material is a perfect match to the silk cloth used to wrap the remains of the Emperor Charlemagne when he was buried in Germany’s Aachen Cathedral (Charlemagne, seen as the first Holy Roman Emperor, died in 814 but was re-buried in the karlsschrein (Charles’s shrine) at Aachen in 1215). The bag at the abbey contains a wax seal, the Great Seal of King Henry III, which was attached to an inventory of the jewels and precious items on Edward the Confessor’s shrine located in the heart of the abbey. It was drawn up in 1267 when Henry III was in financial difficulties and forced to pawn items from the shrine to Italian merchants to raise funds (it is believed the items were all returned within 18 months). The silk used for Charlemagne’s shroud is believed to have been spun in the 12th century in Spain or the eastern Mediterranean and, while the small piece at the Abbey originates from a separate silk, it is understood that it would have been produced by the same weavers on the same loom. The bag can been seen until Easter next year. Admission charge applies. For more, see www.westminster-abbey.org/visit-us/plan-your-visit/the-queens-diamond-jubilee-galleries/.

• A new interactive electric bus display has opened at the London Transport Museum in Covent Garden. The Wrightbus Electroliner display – which has been provided by Transport UK London Bus – is based on an electric vehicle bus type which has been part of the fleet of buses operating in London since 2023. The new display features the front of the bus and includes an interactive driver cab and passenger space. Admission charge applies. For more, see www.ltmuseum.co.uk.
