(CS) Luxembourg's Grand Duke and Grand Duchess concluded their five-day state visit to Turkey on Friday with a tour of Istanbul.

The royal couple visited the Hagia Sophia, one of the city's most iconic sights. Built between 537 and 1453 the building was originally a Greek orthodox basilica, before being briefly turned into a Roman Catholic church and finally becoming a mosque in the 15th Century.

Since the 1930s the building houses a museum, around which Henri and Maria Teresa received a special tour.

They also visited Istanbul's Sultan Ahmed Mosque, also known as the Blue Mosque, before taking an early afternoon flight back to Luxembourg.

It was an eventful trip for the couple, who travelled to Turkey with a large delegation of representatives from Luxembourg's business community, as well as Finance Minister Luc Frieden, Economy Minister Etienne Schneider and Foreign Minister Jean Asselborn.

Received by Turkish president Abdullah Gül with a gala dinner, the visit included a trip to a Syrian refugee camp, business talks, as well as meetings with local ministers, several museum visits and the Atlantic Council Energy and Economic Summit.
