Pope Benedict XVI will visit the Spanish capital Madrid this week as part of World Youth Day celebrations.
It will be the pope's second visit to Madrid this year.
But Deutsche Welle Radio reports that not everybody in the city is happy about the visit.
Some 150 groups plan to protest on 17 August on the eve of the pope's arrival.
The government and sponsors are meeting the cost of his visit at a time when Spain is struggling to come out of recession.
The whole event is costing about 50 million euros. Organisers say most of this will be met through registration fees from the pilgrims, who are also expected to inject 100 million euros into the Spanish economy.
World Youth Day in Madrid is from 16-21 August.
