Caversham is a suburb of Reading with a population of almost 24,000. Caversham was originally part of Oxfordshire until 1911 when county boundaries changed; Caversham legally switched counties and became part of Reading and Berkshire. Back in the 12th century, Caversham was an important place for pilgrims; kings, queens, noblemen and peasants travelled from miles around to worship at the Shrine of Our Lady (a shrine built to honour the Virgin Mary) and the chapel of St. Anne, built on a well whose waters were said to have healing properties. Since the end of the Second World War, Caversham has been the home of BBC Monitoring, which monitors media worldwide from headquarters in Caversham Park House. It is also well known for being the home of Caversham Court, a historic house and garden whose residents and owners over the years include Lady Elizabeth Mosley, the grandmother of Fascist leader Oswald Mosley, and Mary de Pledge, famous for breeding the Caversham strain of Pekingese dogs.
