The listing of a total of 18 historic buildings that are linked to the abolition of the transatlantic slave trade 200 years ago has been amended to highlight their links to the momentous decision by British parliament.

Announcing the new protection for the buildings and monuments, culture minister, Margaret Hodge, stated that the listing is a "timely reminder of how England's involvement in the slave trade is reflected in the built environment".

This year marks the bicentenary of the Abolition of the Slave Trade Act in 1807 and the buildings that have been given greater protection by the government and English Heritage include new listings in Hornsey, Camden, Stoke Newington and Bishops Castle, Shropshire, upgrades for buildings in Stroud and Westminster, and amendments for a further 12 buildings to more accurately reflect their special historic interest.

Ms Hodge explained: "It is important that we acknowledge all aspects of the slave trade, both the people who campaigned against it and succeeded in bringing about the abolition of slavery, and also the people affected by it, the Africans whose lives were disrupted and destroyed."

The buildings and monuments in the listing include the graveyard in Shropshire of the unknown 'native of Africa', The Church of Holy Trinity in Clapham Common and the Buxton Memorial Fountain, Millbank, Westminster. English Heritage started reviewing listed buildings in relation to transatlantic slavery and the abolitionist movement in 2006.
