The Hammers rounded off their spell at Upton Park in style.
Winston Reid netted an 82nd-minute winner to ensure West Ham United's 112-year association with the Boleyn Ground ended on a massive high following Tuesday's 3-2 win over Manchester United.
The Red Devils had threatened to spoil the show when two goals from Antony Martial flipped the game on its head by 72 minutes, following Diafra Sakho's 10-minute opener.
However, Michail Antonio levelled up on 76 minutes, before the New Zealand international grabbed a dramatic win for what was the last ever goal to be scored at Upton Park.
Fireworks illuminated the East London skyline in a post-match party to celebrate its long history at the Boleyn Ground, while there was also live music on the pitch.
When the smoked clear, a host of West Ham stars took to social media to share their sentiments regarding a jubilant night.
Meanwhile, Andy Carroll also paid his tribute on Instagram, posting a photo of himself with Mark Noble alongside the caption: "Farewell Boleyn."
The Irons also moved sixth in the Premier League table as a result, dislodging Southampton from the last Europa League spot as Slaven Bilic's side look set to secure European football for their maiden season at the Olympic Stadium.
