Work begins this week on a new website which will document Norfolk's 40,000 archaeological sites and finds.
Archaeologists excavating the market found the cross foundations
A team of archaeologists from Norfolk County Council are setting up the website with the help of a £203,000 Heritage Lottery Fund grant.
The money will help fund five members of staff who will document sites over two years from the archaeological unit's base at Gressenhall, Norfolk.
Sites to be recorded could include the medieval Market Cross in Norwich.
Recently archaeologists excavating Norwich market before refurbishment work uncovered the foundations of the original cross.
The archaeological team hope to have the website up by the end of 2005 so that people will be able to access the new information from their home computers, in Norfolk libraries or in museums, as soon as it becomes available.
David Robertson, team leader, Norfolk Heritage Explorer Project Team, said: "Preparing interesting summaries on all the county's archaeological sites is a huge and exciting task.
"Hopefully putting the information onto the internet will open up Norfolk's rich heritage to a wider audience than ever before."
Robyn Greenblatt, Heritage Lottery Fund's manager in the East of England, said: "This project will create an invaluable resource that will help open up Norfolk's archaeological treasures to a much wider audience."
