The ground was first purchased by the Munster Branch of the IRFU in the late 1930s, and in use by the early 1940s. Named for Jimmy Musgrave, a past-president of the IRFU, this early ground incorporated a small pavilion between two pitches. Terracing and seating were later added. Dolphin and Sunday's Well rugby clubs were tenants from the outset, though the ground also sometimes hosted provincial and international games. The latter included a number of notable Munster Rugby performances against touring international teams, including Australia (in 1967), the All Blacks (in 1973), and Australia (in 1992) when the then world-champions were defeated at the ground.
