The saint buried in the heptagonal construction is revered mainly by the 70,000 strong Alevi community of Bulgaria. The Alevis, an offspring of Islam, believe that all religions are equal. Unlike traditional Sunni Muslims, they drink alcohol, their women do not cover their heads and they do not go to mosques to pray.
Their beliefs are esoteric and full of symbols: consider that the turbans depicted on men's tombstones always have seven straps.
