• Leicester Square officially reopened last night following a £15.3 million transformation which has seen every paving stone replaced, new plants, and 40 new water jets placed around the Grade II listed fountain and statue of William Shakespeare. The 17 month makeover also included new lighting, new seating and a refurb of the underground toilets. The square – which owes its name to Robert Sidney, the 2nd Earl of Leicester, who purchased this land in 1630 and, after building himself a mansion, kept aside part of the land for public use – now welcomes as many as 250,000 tourists a day and is known as one of the world’s premiere sites for the release of new films.

• The Royal Academy of Arts is marking the Queen’s Diamond Jubilee with a new exhibition opening tomorrow which features a selection of paintings by Royal Academicians elected during the early part of the Queen’s reign. The Queen’s Artists will include works by Jean Cooke, Frederick Gore and Ruskin Spear and will be displayed in the Reynolds and Council Rooms. Meanwhile The Saloon will house a collection of sculptures, paintings and drawings prepared by Royal Academicians for British coins and royal seals on loan from the Royal Mint Museum. The collection includes portraits of the Queen by Edward Bawden and Sir Charles Wheeler which have never before been shown in public, and Sir Anthony Caro’s new coin design of the London 2012 Olympic Games. Over in the Tennant Gallery, The King’s Artist’s George III’s Academy, will look at the king’s role in the foundation of the academy in 1768 and his influence in selecting the first artists. Highlights include portraits of King George III (pictured) and Queen Charlotte painted by the academy’s first president, Sir Joshua Reynolds. Admission charge applies.

• The Royal Parks’ Shire horse, Jed, retired last week after a decade of service working in Richmond Park. The Queen presented a commemorative retirement rosette to Jed who was born in 1993 and joined the Royal Parks from Bass Brewery in Burton upon Trent almost 10 years ago. Horses have been used in Richmond Park since it was enclosed by King Charles I in 1637. The horses took a break in 1954 but the Shires were reintroduced in 1993 as a way to sustainably manage the parkland. For more on Richmond Park, see www.royalparks.org.uk/parks/richmond-park.

• On Now: The horse: from Arabia to Royal Ascot. This major free exhibition at the British Museum is part of the august institution’s Diamond Jubilee celebrations and traces the history of the horse from domestication around 3,500 BC through to present day, with a particular focus on Britain’s equestrian tradition, from the introduction of the Arabian breed in the 18th century to events like Royal Ascot. Highlights include one of the earliest known depictions of horse and rider – a terracotta mould found in Mesopotamia dating from around 2000 to 1800 BC, a cylinder seal of Darius dating from 522 to 486 BC depicting the king hunting lions in a chariot, a 14th century Furusiyya manuscript, an Arabian manual of horsemanship, and the 19th century Abbas Pasha manuscript, the primary source of information about the lineage of purebred Arabian horses acquired by Abbas Pasha (mid-nineteenth century viceroy of Egypt). The exhibition is being held in Room 35. Runs until 30th September. For more, see www.britishmuseum.org.
