Champions Celtic beat Hearts to become the first team to complete a Scottish top-flight season unbeaten for 118 years.
Leigh Griffiths and Stuart Armstrong secured a 34th win of the campaign for Brendan Rodgers’ side, who were then presented with the Premiership trophy.
The feat was last achieved by Rangers in 1898-99, over an 18-game season.
And Celtic join Arsenal (2003-04) and Juventus (2011-12) in being unbeaten over a 38-game league season.
Rodgers’ side, who won the League Cup in November, will attempt to win the club’s first domestic treble since 2001 when they take on Aberdeen in Saturday’s Scottish Cup final.
Celtic, who have won six top-flight titles in a row, are unbeaten in 46 domestic games this season (38 in league, eight in cups), and 47 domestic matches overall including the final league game of last season.
And they are unbeaten in 31 games in all competitions since losing to Barcelona in the Champions League on 23 November.
With the win and goals against Hearts, Celtic set new records for the Scottish Premier League/Premiership era, including goals, points, wins and margin of victory.
