Prince of Wales and the Duchess of Cornwall rode a city centre tram as they arrived in Seville, southern Spain.
The royal couple are on the final day of an official visit to the country where they have been hosted by the crown prince, Felipe, and his wife Letizia.
After arriving in the Andalusian capital, famous for its architecture and arts, Charles and Camilla were met by regional president Jose Antonio Grinan Martinez at his offices in the 17th-century San Telmo Palace.
The prince and the president held a private meeting where they discussed Andalucia's Three Cultures Foundation, a project which builds bridges between the Christian, Jewish and Muslim cultures in the region.
Key to the scheme's success is co-operation between the region and its southern neighbour Morocco, where Charles and Camilla will visit on Monday. There are around 700,000 Moroccans living in Spain and the prince attended a seminar staged by the Foundation called "Unlocking Muslim Potential".
During the prince's meeting, the duchess toured the palace's Baroque Chapel, which has been restored to spectacular effect.
Camilla spent 10 minutes in the chapel venturing to the top of the altar and waving through a glass window at the photographers and staff below.
As her husband arrived, Camilla told him: "This is a fabulous place. I'm very lucky I've had a very good tour. It's beautiful."
The couple then signed a visitors' book, the prince reaching for a pen from the inside of his jacket as one had not been left ready for them.
The couple also called in on the Mayor of Seville, Alfredo Sanchez Monteseirin, who met them at the steps of the Town Hall.
