The Terrace Tunnel was open to the public on Sunday 24th March for a one-off chance to walk through it to mark the end of its upgrade, the first upgrade since it was opened in 1978.
Tunnels Alliance chose Wellington Children's Hospital as their charity while the Tunnel was undergoing its makeover.
Members of the public who attended Sunday's walk through donated to the Wellington Children's Hospital Centenary Appeal.
Thanks to all the Foundation Volunteers who turned out to help on a beautiful Wellington night.
