Swindon OASIS is shut down now, not sure what they're doing with it....
I live in Swindon and have done for 5 years, I moved from Bristol upto here as my wife is from here and is very family focused than me, it's alright but if I was given the choice I'd move back to Bristol... I work for the council and have visited most of the areas here and tbh they're not as bad as people make out, maybe a few years back but now it's just the young ones upto the usual stuff you get everywhere these days....
It's more the lack of any future vision/plan for the town. You'll get anti-social youths wherever you go up and down the country.
IIRC the plan for this indoor ski slope + complex was bought to the table a good 10-15 years ago, plans were given the go-ahead but they couldn't secure an investor to put up the money so the idea got shelved.
It then popped up again maybe 3-4 years ago, and again plans were given the go-ahead, i think this time round they actually did get an investor who was willing to put up the money. And of course covid happened and last i heard the investor had pulled out, so would expect the idea to get shelved again.
The problem is with the town losing big shops and big employers, it's not really a welcoming sight for an investor to plough £100mil into various projects.
As Mysterae says, it's now pretty much a commuter town for trains to Bristol/Reading/London as it's directly on the high-speed line it's got very good links in both directions.
Only joking, got friends there and it's nice but we picked Chippenham because of the easy access to the M4 for Bristol and Swindon.
