Part of Wilberforce 2007, the Walking with Wilberforce Heritage Trail is a journey through Hull's Old Town, via twelve important landmarks related to William Wilberforce and the theme of freedom. Along the trail is the Humanitarian Wall, at the Wilberforce Institute for the study of Slavery and Emancipation, constructed in 2006 to commemorate worldwide actions for human rights and justice. The ceramic markers, inspired by the Sankofa bird, were designed especially for the trail by three community and art groups from Hull's Africa Forum, from Hull College ceramic students and from local schools working in collaboration with two local ceramic artists. The trail was launched with a celebration of African culture led by students from Hull schools and the local Congolese community.
