Critics of a new super prison in Wrexham believe violence, drug abuse and disorder will be inevitable at a site of its size and scale.
Supporters of the project argue it'll be a boost to the local economy and create jobs. But experts say problems at newly built prisons of similar sizes prove its difficult to keep inmates under control, as Alexandra Lodge reports.
Concerns will be raised later over the size and scale of the plans for a new super-prison in Wrexham by a panel of experts at an event in Cardiff Bay.
The UK government says the jail will cover 26 hectares at the former Firestone factory on the Wrexham Industrial Estate, house around 2,000 inmates and employ nearly 800 people.
Those who welcome the plans say it will be beneficial for local economy.
But opponents say the prison will bring disruption and argue that small prisons can find it easier to perform better than large ones. They also say that the development would have a detrimental effect on existing Welsh Government responsibilities.
The Welsh Secretary has been hearing first-hand why some people want to relocate rather than live next to a so-called 'super prison' planned for the outskirts of Wrexham.

David Jones MP is urging local companies in north Wales to seize the business opportunities presented by the proposed development of a 'super-prison' in Wrexham.

Pending planning approval, the work at the site in Wrexham should start this summer. £250m is being invested in the development.
Prisons Minister Jeremy Wright and Secretary of State for Wales David Jones will visit the former Firestone factory site where the prison is scheduled to be built.
They will also meet with local companies and the prime contractors bidding for the construction contract.
Some people living in the local area oppose the plans for the 'super-prison' saying it will have a negative effect on the community.
A £100m prison is to be built in North Wales. The Chief Secretary to the Treasury, Danny Alexander, made the announcement as part of a series of investments in infrastructure. Welsh Secretary David Jones has welcomed the news.
A new 'super-prison' to hold more than 2,000 inmates could be built in North Wales, the Ministry of Justice has announced.
The announcement comes as the Government begins a feasibility study for upgrading the UK's prisons.
The new prison - which larger than any facility in the UK - is likely to be located in North Wales, the North West or in London.
Four new 'houseblock' prisons will also be built - one of which will be situated at the HMP Parc site in Bridgend.
