Wikipedia has an article about the Lion Yard Shopping Centre that advises:

The Lion Yard Shopping Centre is a city centre undercover shopping centre in Cambridge, England. It predates and is significantly smaller than either the Grafton Centre or the Grand Arcade. The latter connects directly to the Lion Yard, which is in the city centre. The Grafton Centre is situated just outside the city centre, however it boasts large shops such as Debenhams which the Lion Yard does not have, due to its confined location.

Construction work on the centre, which is bounded by St Andrew's Street, Corn Exchange Street, and Petty Cury, commenced in 1970 and the centre contained a library, multi-storey car park and magistrates' court. For many years a central feature of the atrium was a large white pillar with the statue of a large very red lion on the top of it, safely out of easy reach. This recalled the Red Lion pub which had occupied the site until demolished in 1969.

The Lion Yard was significantly refurbished in the late 1990s/early 2000s. A recently constructed undercover mall, the Grand Arcade, adjoins Lion Yard on its south side: the two are interconnected.

The main shopping mall is centred around an atrium which benefits from 4 entrances and exits. The retail element is concentrated on the ground floor however the Central Library can be accessed from the first floor of Lion Yard along with retailers Ellis Brigham, The North Face and New Look.

The Centre consists of a three storey office block (Lion House and St George House), an undercover external colonnade taking up one half of Petty Cury, external boutique shops opposite St Andrew The Great Church, many great high street retailers internally along with housing the 7th busiest library in the UK. Although it is the smallest and oldest of the three shopping centres, continual investment in the scheme has ensured that the Centre continues to draw in the crowds.

The Brit Royals website has an article about Princess Anne that tells us:

Princess Anne was born on 15 August 1950 at Clarence House in London. She is the second child and only daughter of Queen Elizabeth and Prince Philip. She was baptised at Buckingham Palace on 21 October 1950 by the Archbishop of York. She is styled Her Royal Highness Princess Anne of Edinburgh. As a child she was more bossy and vivacious than her older brother Charles.

Princess Anne was educated privately at Buckingham Palace, and then at Benenden boarding School in Kent. She attained two A levels but was happiest in her love of the outdoors and horse riding. On leaving Benenden in 1968 she entered public life, and at 20 became president of Save the Children Fund on whose behalf she has worked tirelessly and visited over 70 counties. She is also Commandant-in-Chief of St John Ambulance, founded the Princess Royal Trust for Carers and is an official with over 200 charities. On 13 June 1987, the Queen bestowed her with the title of Princess Royal the title traditionally given to the monarch's eldest daughter. She carries out the most engagements of any member of the Royal Family, and holds a number of honorary appointments with the British Armed Forces and of several Commonwealth countries.

Her boyfriends included Andrew Parker Bowles (later husband of Camilla), and Richard Mead Olympic Champion at three-day eventing. On 14 November 1973 Princess Anne married Mark Phillips in Westminster Abbey, London. He was a Lieutenant and later Captain in the Queen’s Dragoon Guards. He was offered but turned down an Earldom so their children have no courtesy titles. Their son Peter Phillips was born in 1977 and daughter Zara in 1981. In 1974 she was the target of a kidnap attempt in Pall Mall London when a deranged individual tried to bundle her into a car and hold her for ransom. In 1989 the Princess and Mark Phillips announced their intention to separate and they were divorced on 28 April 1992. She remarried Timothy Laurence, a naval Commander, on 12 December 1992 at Crathie Kirk a Church of Scotland church near the Balmoral Estate.

She has always been keen on horses and equitation events. In 1971 she won the individual title at the European Championship three-day event, and was voted the BBC’s Sports Personality of the year. She won a silver medal in the individual and team events at the 1975 European Eventing Championship, and in 1976 participated with the British Team in the Montreal Olympic Games. She is a British representative in the International Olympic Committee, and a member of the London organising committee for the 2012 Olympic Games.
