<P> In 1936, the previously dirt - covered yard was paved . The yard was part of the most violent escape attempt from Alcatraz in May 1946 when a group of inmates hatched a plot to obtain the key into the recreation yard, kill the tower guards, take hostages, and use them as shields to reach the dock . </P> <P> Inmates were permitted out into the yard on Saturdays and Sundays and on holidays for a maximum of 5 hours . Inmates who worked seven days a week in the kitchen were rewarded with short yard breaks during the weekdays . Badly behaved prisoners were liable to having their yard access rights taken away from them on weekends . The prisoners of Alcatraz were permitted to play games such as baseball, softball and other sports at these times and intellectual games such as chess . Because of the small size of the yard and the diamond at the end of it, a section of the wall behind the first base had to be padded to cushion the impact of inmates overrunning it . Inmates were provided gloves, bats, and balls, but no sport uniforms . In 1938, there were four amateur teams, the Bees, Oaks, Oilers, and Seals, named after Minor League clubs, and four league teams named after Major League clubs, the Cardinals, Cubs, Giants, and Tigers . Many of the inmates used weekends in the yards to converse with each other and discuss crime, the only real opportunities they had during the week for a durable conversation . </P> <P> The Warden's House was the home of the penitentiary's warden . It is located at the northeastern end of the Main Cellblock, next to Alcatraz Lighthouse . The 3 - floor 15 - room mansion was built in 1921 according to the Golden Gate National Recreational Area signpost, although some sources say it was built in 1926 or 1929 and had 17 or 18 rooms . </P> <P> Between 1934 and 1963, the four wardens of Alcatraz resided here, including the first warden, James A. Johnston . A house of luxury, in stark contrast to the jail next to it, the wardens often held lavish cocktail parties here . The signpost at the spot shows a photograph of a trusted inmate doing chores at the house for the warden and that the house had a terraced garden and greenhouse . The mansion had tall windows, providing fine views of San Francisco Bay . Today, the house is a ruin, burned down by Native Americans during the Occupation of Alcatraz on June 1, 1970 . </P>
