The win marked the club’s first domestic trophy in 70 years, with the streets turning into a sea of black and white for an open-top bus parade.
It was estimated ahead of the event that as many as 150,000 fans were due to line the streets for the parade.
An estimated 150,000 fans then gathered at the park Town Moor for a ticketed event, which saw players gather on stage to lift the trophy, recreating what they did at London’s Wembley Stadium nearly two weeks ago on 16 March.

For manager Eddie Howe, Saturday’s event was an emotional moment as the city honoured him with a massive banner, unfurled outside St James’ Park – the team’s home stadium.
Goalscorer Dan Burn, a childhood fan of Newcastle, also couldn’t hide his emotions, telling Sky Sports News: “I don’t know what I was expecting, but it is everything I have ever dreamed of.
“It is something I will never forget.”
Joining the team on the open-top bus were Newcastle-born TV icons Ant and Dec (Ant McPartlin and Declan Donnelly).
The pair, who both support the Premier League team, posted a clip of them following the squad to the bus as McPartlin shouted “let’s get ready to rumble” in reference to the pair’s hit single as PJ and Duncan.
In another social media post, Donnelly said: “Well, we’re about to start the parade. I don’t know how we’ve sneaked on here, how have we done this? We just followed the team on and we’re on the parade.”
McPartlin then began to chant “ole, ole, ole, ole”, while in another video the pair could be seen overlooking fans as the bus passed the club’s St James’ Park ground.
As the bus and crowd approached the Town Moor site, white smoke blanketed the area as the crowd sang Hey Jude, replacing the word Jude with Geordies.
The celebration ended with a drone show over the park, which sponsor of the team Sela, had teased as a “spectacular surprise” earlier in the day.
The drones morphed into various images and words, including a Newcastle shirt with the words “making history” underneath.
