Arguably Bulgaria’s most beautiful mosque, and definitely the largest still used, Shumen’s Tombul Mosque (1744) is also called the Sherif Halili Pasha Mosque. Its Turkish nickname, tombul (plump), refers to its 25m-high dome. The 40m-high minaret has 99 steps. Local Muslim belief says that the courtyard fountain gushes sacred water.
