The Cadburys were also concerned with the health and fitness of their workforce, incorporating park and recreation areas into the Bournville village plans and encouraging swimming, walking and indeed all forms of outdoor sports. In the early 1920s, extensive football and hockey pitches were opened together with a grassed running track. Rowheath Pavilion served as the clubhouse and changing rooms for the acres of sports playing fields, several bowling greens, a fishing lake and an outdoor swimming lido, a natural mineral spring forming the source for the lido's healthy waters. The whole area was specifically for the benefit of the Cadbury workers and their families with no charges for the use of any of the sporting facilities by Cadbury employees or their families.
