The Archbishop of Canterbury will visit Truro Cathedral for a day of prayer next month.
The new Archbishop, Justin Welby, is encouraging others to join him at the cathedral on March 18 ahead of his enthronement on March 21.
A spokesman for the cathedral said the purpose of the Archbishop's journey was to pray and to encourage others to pray with him and said he was keen to welcome everyone across Cornwall and the Isles of Scilly.
The Bishop of Truro, the Right Reverend Tim Thornton, said: "This is a great privilege for us, so do come to the Cathedral and join with the Archbishop in prayer on Monday 18 March.
"As we journey through Lent, considering our own discipleship, what better time to pray for the him as he takes this momentous step on his journey - and we can also pray for ourselves and for the wider church.
"Prayer is a radical action with enormous and unforeseen consequences. Prayer enables us to recognise that we are not in control but that God is.
"And so prayer allows us to be transformed into the people God wants us to be."
Archbishop Justin will be spending part of the day praying on his own and, at times, with other people.
