Prizren, considered the most beautiful city in Kosovo, offers a picturesque old town with the Kalaja Fortress, the Sinan Pasha Mosque, and the Bistrica River, making it ideal to visit during spring.

Designed by the famous Ottoman imperial architect Mimar Sinan (who also designed the Süleymaniye Mosque) and completed in 1563, the structure was dedicated to the Grand Vizier Rüstem Pasha.
