School swimming was introduced in the city in April 1875 following a campaign by Joseph Chamberlain, which commenced at a Meeting of the Council on 10 November 1874. Following co-operation between the City of Birmingham Baths Department and the Birmingham School Board, schools were able to buy books of tickets to allow pupils to swim under the guidance of teachers at pools. Bowling has long been a popular tradition in Birmingham with bowling greens and quoit grounds often attached to public houses. In 1778 there was one at the "Salutation" inn, at the bottom of Snow Hill; in 1741 there was also one at the "Hen and Chickens" in the High Street. A new green was opened at the "Union Tavern" on Cherry Street on 26 March 1792. There was also a green at Aston Hall and Cannon Hill Park during the Victorian era. In 1825 a bowling green was laid out at the corner of Highfield Road and Harborne Road, for "a very select party" of Edgbastonians. Bowls is still played in the city today with the existence of The Northfield & District Bowling Association and The Yardley Wood & District Mid-Week Bowling Association. Greyhound racing is a popular event in the city with a large stadium at Perry Barr Stadium. A trust has been established in Perry Barr for retired greyhounds. Former stadiums are Hall Green Stadium (1927-2017), Kings Heath Stadium (1927-1971) and Birchfield Ladbroke Stadium (1928-1984). Ice Skating Rinks were opened at the Lower Grounds 1 May 1875; at Bingley Hall, 2 October 1875; at Moseley, 6 December 1876; and at Handsworth, 8 October 1877; and, for a time, the amusement was exceedingly popular, more than one fortune accruing from the manufacture of patent and other roller skates. One of the most noteworthy feats on the slippery rinks was the skating of 200 miles in 24 hours by a Mr. F. Betteridge at Bingley Hall, 20 August 1878. Birmingham's last ice rink closed in 2003 and a project began campaigning for a new rink. In the winter of 2005 one of the largest temporary outdoor ice skate rinks in Britain was erected on Centenary Square. Another rink was constructed in the square in the following year. Ludosport, is an International Lightsaber Combat Academy, teaching light saber combat as an international competitive sport. Classes started in Birmingham in January 2016 and pupils train on a weekly basis, with local instructors who have trained with the parent organisation in Italy "Ludosport International".
