The Bittersweet programme by the Gateway Gardens Trust involved 80 free guided garden visits over two years, around more than 30 gardens in Wales with a range of community groups, schoolchildren and lifelong learners. The themes of the visits and a mobile exhibition were the links between the slave trade and historic gardens, their makers, what they planted, Welsh abolitionists and the wider links with local communities in Wales. Historic gardens provided the starting point, looking at how everyday vegetables and fruits - beans, potatoes, tomatoes etc. - first reached the UK from the Americas. The project also looked at the history of afternoon tea, and the links between sugar, cotton and tea and slavery. The groups reflected on how many industries, grand houses and gardens were built from wealth linked to slavery, such as Cyfarthfa Ironworks in Merthyr and the expansion of the slate industry at Penrhyn Quarry. Early 18th century-style newspapers were produced, aimed at schoolchildren and adults.

Gardens involved included Cardiff’s Bute Park, Swansea’s Singleton Park, the National Botanic Garden in Carmarthen, Gwydir Castle in Llanrwst, Dyffryn Gardens, Portmeirion, Penrhyn Castle, Picton Castle, Dinefwr Park and Castle and Aberglasney Gardens.

Everywhere in Chains was an umbrella project created for the bicentenary commemorations in 2007, by a collaboration between Amgueddfa Cymru - National Museum Wales, the National Library of Wales, University of Wales, Bangor and CyMAL: Museum Archives and Libraries Wales (part of the Welsh Assembly Government). An exhibition explored Welsh involvement in slavery, especially focusing on the transatlantic slave trade and its abolition, the Black presence in Wales, and legacies of slavery. This was shown at the National Waterfront Museum in Swansea from May to November 2007 before touring to Wrexham County Borough Museum. The touring version of the exhibition was funded by the Welsh Assembly Government. The exhibition in Wrexham included discussion of the painting 'A Negro Coachboy', thought to commemorate a black servant of John Meller, owner of the Erddig estate in the 18th century.

Alongside the exhibition, the Everywhere in Chains programme also included lectures, formal learning activities and performances. An educational pack was produced by CyMAL and distributed to every school in Wales in 2009-2010. A community project created a forum in which participants from many cultural backgrounds could voice their ideas about enslavement. The Everywhere in Chains Community Heritage Toolkit captured the learning from this project. The toolkit, launched in 2009, was produced to help individuals, groups and organisations to work with culture and heritage providers to undertake projects focused on the role of Wales in the transatlantic slave trade and issues of modern slavery.
