Most Rev John Sentamu announced Holy Trinity Church will become a Minster on 13th May 2017 in a special inauguration service.
He announced two years ago that the church would be upgraded if a major renovation was successful. Holy Trinity managed to raise £4.5m in order to begin them.
It's being upgraded partly because Hull is set to celebrate being named the UK's City of Culture for 2017.
The award will be commemorated with special events across the city and there are hopes being named a City of Culture will lead to greater long term investment in the East Yorkshire region.
Dr Sentamu was joined by the Bishop of Hull, Rt Rev Alison White, in laying paving stones in Trinity Square (video, below) as he announced Holy Trinity Church would become a minster.
What does becoming a Minster actually mean?
The status of Minster is an honorific title bestowed on major churches of regional significance in the Church of England, to reflect their importance and contribution to the local communities they serve.
It means that the status of Holy Trinity, which is England's largest parish church, will be elevated 725 years after it was founded in 1292.
Dr Sentamu said: "Two years ago I came here and urged people to dream big about the possibilities for Holy Trinity and for the city of Hull as a whole and to give their all to make the vision a reality.
"It is fantastic to see so many people and organisations getting behind the development project and providing the funds to drive it forward.
"Holy Trinity is doing great things to reach out to the local community and make the mission of the Church relevant to the daily lives of the people of Hull.
"The development project builds on that wonderful work and will ensure Holy Trinity remains fit for purpose as a magnificent place of worship and a welcoming, supportive home for everyone in the heart of the city."
