THE star of Channel 4’s Time Team, archaeologist Phil Harding, will unveil the new visitor centre at Butser Ancient Farm.
More than £300,000 has been raised to create a fitting gateway to the site, which is the only place in Western Europe to present Iron Age Houses and a Roman Villa alongside prehistoric livestock, crops and fences to depict life in Britain 2,000 years ago.
The centre is named after Janus, the Roman god of gateways.
The fully-accessible building is now the hub of the farm, which is in Chalton, near Waterlooville.
Butser’s director Maureen Page said: ‘We are so grateful to all our funders. Without their help this would not have been possible.’
The opening ceremony is at 2pm and is for invited guests only.
