Peterborough Cathedral tunnels reveal site's true age

Next year plans were in place to celebrate Peterborough Cathedral's 900th anniversary - dating it to just before the Norman Conquest.

However, inscriptions found in catacombs deep beneath the Gothic architecture are creating a stir.

The foundations are believed to date from the Anglo Saxon era, but historians now think there could have been a Roman temple there first.

That means the site could be 1,000 years older than thought.
