Playing tennis, taking the kids and making priceless memories - you've been sharing your favourite moments from life at the Seaburn Centre.
Demolition work on the building is continuing this week after being halted at the end of 2017, due to a nesting group of starlings. An ecology survey had to be carried out before work could continue.
The centre opened in the mid-1980s, but closed in March after Sunderland City Council said it was "no longer commercially viable".
Pop-up attractions, including an outdoor cinema, restaurants and cycle hubs form part of proposals approved by councillors in April, to enhance tourism opportunities in the city.
These plans are aimed at keeping the site in use until permanent plans are lodged with the council.
As parts of the building are torn apart by machinery, dozens of you took a trip down memory lane to share some of your stories of visiting the Seaburn Centre as a child, with your own children, and in groups of friends.
Here are some of your memories from social media:
Darrin Forse: "Putting the sound system in with my dad when it first opened."
