Gun Wharf is basically the re-development of Portsmouth Harbour, done around the Spinnaker Tower and the Millennium Walk (a seafront and dockside footpath). The shopping centre is only part of it. Definitely not car-only, Portsmouth Harbour railway station is smack bang in the middle (Gun Wharf to the right, Historical Dockyard to the left).As others have asked, can you clarify who or what is Gun Wharf? Most people (myself included) have never heard of it prior to this thread. Is it something only people who drive know about (my best guess)?
Couldn't believe it the first time I went there when I remember what it used to be like.
