LIVERPOOL, England - Eric Lynch started walking the streets of Liverpool in search of his past, a story he now shares with visitors who want to probe the city's involvement in the slave trade.

"The problem in Liverpool, it's what I call a hidden history. Nobody wants to talk about it," says Lynch, a black Liverpudlian who launched his walking tours in 1970.

He points out the frieze around the top of the Town Hall, where images of African spears, barrels of rum, sugar and cotton recall how ships from Liverpool carried slaves from Africa to the New World and brought back cargoes from the plantations.

Liverpool, which became the greatest slave-trading port in Europe in the 18th century, has been in the spotlight this year as Britain marks the 200th anniversary of the abolition of the slave trade in its territories.

On Aug. 23, the city will open a new International Slavery Museum, greatly expanding the current exhibition in the Merseyside Maritime Museum on the Albert Dock.

Lynch says people who join his tours sometimes become upset by what they learn, but he says that isn't his objective.

"I don't do it in a vindictive way. I tell people, you didn't do it, I didn't do it, but you have a right to this knowledge."
