28 August 2014 Last updated at 08:17 BST
The Nato summit is being held in Newport, Wales and an estimated £50m is being spent on security measures, including an eight mile fence around the venue where the state dinners will be hosted.
More than 150 world leaders, including Barack Obama, will fly in and attend the two-day event at The Celtic Manor.
Residents around the venue are expecting chaos and disruption and some are unhappy about this, as Hywel Griffith has been finding out.
