When Eger was taken by the Turks, this minaret was erected. Eger became the capital of one of the Ottoman provinces and housed at least four madrasas - Islamic schools.
Islam dominated the country, though Christianity and Judaism were tolerated. Hungary was now called Madaristan.
Here is music from the Ottoman court by my favorite classical oud player, Munir Nurettin Beken.
Gul Baba was a Sufi mystic, poet, and companion to Suleiman the Magnificent who conquered Hungary and turned the country into an Ottoman country - Madaristan - for 150 years. When Gul Baba died shortly after the conquest of Buda, the Sultain buried him on there. His mausoleum, along with the Turkish baths are memorials to the Turks and their Islamic traditions.
Gul Baba's tomb was built in 1543 in the Buda hills. Today it is fully restored, with a beautiful garden, and owned by the Turkish government. It is the northern most Islamic pilgrimage site in the world, and the only one in Western and Central Europe.
