Hosted by Fylde Council, the Coronation After Party featured live music from 2pm-5pm, a roaming royal theatre, and a photo opportunity with the 'King'.
There was also food and drink stalls, afternoon tea, boat rides – on an aptly magestic Swan boat! – and Adventure Golf.
Take a look at the scenes from the day featuring partygoers and performers as they continue the celebrations.
