Wakefield Council and Pontefract Civic Society have signed a 'Memorandum of Understanding' which sets out how they will work together to promote the historic town.
The document is a formal pledge to work collaboratively and with key partners to raise the profile of the town locally, regionally and nationally.
Both organisations will be encouraging tourists to visit Pontefract and see its attractions, including Pontefract Castle which is benefiting from the £3.5 million Key to the North project to conserve the building and which has recently seen the opening of a new Visitor Centre and café.
Cllr Denise Jeffery, Cabinet Member for Economic Growth and Regeneration at Wakefield Council, signed the Memorandum with Paul Cartwright, Chairman of Pontefract Civic Society.
The formal signing of the document took place at Pontefract Castle.
Cllr Peter Box CBE, Leader of Wakefield Council, said: "The Council has been working with the Civic Society for many years. It has been instrumental in helping us to delivering many positive changes.
"Having the Memorandum of Understanding in place strengthens a crucial link between the Council, the Civic Society, residents, businesses and community groups that are based in our great town."
Cllr Denise Jeffery added: "Pontefract Castle is just one example of how the Council has joined forces with partner organisations to strengthen our offer and this is an approach that we know works for the good of everyone."
