In the 17th century, the Kersal Moor races were the great event of the year. They usually took place around Whit Week when large numbers of people turned the area into a giant fairground for several days. The moor was also used for nude male races, allowing females to study the form before choosing their mates. Indeed, in the 18th century, Roger Aytoun, known as "Spanking Roger", later a hero of the Siege of Gibraltar, acquired Hough Hall in Moston, through marriage after such a race. Kersal Moor was also host to one of the great political events of the 19th century, when it was the meeting place for the largest of the Chartist Assemblies attended by at least 30,000 people in September, 1838 and again in May, 1839. It was also the site of one of the first golf courses to be built outside Scotland. Kersal Links opened in 1818, and was the oldest golf course between the Thames and the Tweed until it closed in 1960. The Kersal Moor races began prior to 1680 and continued, with various interruptions, until 1847 when the course was switched to the other side of the River Irwell, to Castle Irwell, where it remained until 1963. In 1961 the Members' Stand at the Castle Irwell Racecourse was opened and contained the world's first executive boxes. The architect for the racecourse, Ernest Atherden, showed this to the directors of Manchester United who opened their first executive box in 1965, and hence began the modern corporatisation of sport.
