Located on Sharia Suyufiya, Cairo.
One emblem above the entrance gate.
Upper field with a pen-box, central field with a cup between a pair of polo-sticks, lower field with a fleur-de-lis
Following Leo Mayer (Saracenic Heraldry, p. 228-229) and Michael Meinecke (Zur mamlukischen Heraldik, p. 271-273), this emblem can’t be the one of emir Ṭāz as he died in 763/1362 because it displays the emblems’ composition of emirs of sultan Īnāl and is therefore a century younger than the palace.
Possible dating: between 857/1453 and 865/1461
