Local legend tells us that Kasap ƒlyas was the chief butcher/meat provider to the Ottoman army that conquered Constantinople in 1453 and that
in recognition of his services, the sultan bestowed upon him a large plot of
land. On this plot of land he first built a small mosque bearing his name
and endowed it. Around this local mosque, goes the legend, a whole neighborhood bearing his name then took shape. The elderly inhabitants of
Kasap ƒlyas still recount the many foundation myths concerning Kasap İlyas
and his arrival to the neighborhood, as well as his many exploits, religious
and otherwise. Kasap ƒlyas has grown into a sort of mythical figure and he
has been surrounded by an aura of sanctity by the locals for quite a long
time. His deed of trust (vakfiye) was set down in 149417 and his small shrine
standing in the small graveyard beside his mosque bears the date of 1495
as the date of his passing away. The present-day Kasap İlyas mosque was
almost totally rebuilt after the 1894 earthquake. Of the original structure,
nothing much remains
