Atletico were leading Barca by six points at the top of the Liga Iberdrola heading into the game but second-half goals from Asisat Oshoala and England international Toni Duggan halved the deficit with six games remaining.
The previous attendance record for a women's game in Spain was Athletic Bilbao's game with Atletico Madrid in the Copa de la Reina on Jan. 30, when 48,000 supporters crammed into the San Mames stadium in Bilbao.
The former world record attendance for a women's club match was a game between Mexican sides Monterrey and Tigres in 2018, where 51,000 fans showed up.
The biggest attendance for any women's game remains the 1999 World Cup final between the United States and China which saw 90,000 fans flood into the Rose Bowl Stadium in Los Angeles.
