Bells have rung across Bristol to mark the bicentennial anniversary of the abolition of slavery act.
St Mary Radcliffe rang bells for three hours
Hundreds of people rung bells at College Green, Portland Square, Westbury-on-Trym as well as at Bristol Cathedral and St Mary Radcliffe.
Bells Unbound is a worldwide initiative which started in Bristol.
A ceremony in Bristol Cathedral was interrupted by protesters belonging to Operation Truth 2007, who were chanting "not in our name" outside.
A police officer led protestor Jendayi Serwah, 41, from the cathedral after he started to bang a drum inside.
"We feel this ceremony is totally inappropriate - 1807 did not bring anything for enslaved Africans," said Mr Serwah.
"Where are the tickets for the African people of Bristol? We are left standing outside."
The Bishop of Bristol, Rt Rev Mike Hill, said it was important that people remembered events in the past which were not victorious.
"Remembering is not unimportant and every year we turn up to remember the two great wars.
"I just think sometimes we're a little less comfortable remembering things that are perhaps not so glorious and victorious in our past but that doesn't mean it is wrong to remember them."
A group of 12 people from the protest group affected the procession led by African drummers from the Watershed to the cathedral on Sunday afternoon.
