Pope Francis, who will spend seven hours in Hungary, will meet Orban at the Museum of Fine Arts in Budapest.
It is a delicate meeting since the head of the Catholic Church has strong differences with the ultra-nationalist leader on his immigration policy and on the harsh Hungarian laws against homosexuality.
According to the official program, the meeting will last about half an hour, the President of Hungary, János Áder, will also attend and no speeches will be made.
The Argentine pope wanted to add a stage of hours to Hungary to celebrate the closing mass of the 52nd International Eucharistic Congress scheduled in Budapest.
That same day, the pope will travel to Slovakia, where he scheduled important meetings with the most emblematic communities of that country: the Jewish and the Gypsy, decimated after the Second World War.
Francis will also visit Bratislava, the capital, the cities of Presov and Kosice, preside over a Byzantine liturgy and meet young people in a stadium.
