On 17 February 1957, Real Madrid beat Deportivo de La Coruña to launch a record 121-game home unbeaten streak in the league.
It was Madrid's first home league match since a loss to Atlético Madrid two weeks earlier and they responded by beating Deportivo 1-0 with a goal from forward Enrico Mateos in the 25th minute. They then won their last three remaining home games and claimed the league title.
Amazingly, they continued to defend their home ground in the league for another eight years, going unbeaten over a span of 121 matches that carried them to another six La Liga titles. Of those 121 matches, only eight were draws; they won the remaining 113.
The streak's last game came on 21 February 1965 with a 6-1 win over Real Betis and it ended on 7 March with a loss to Atlético, 0-1.
