The Shakespeare funerary monument is located inside Holy Trinity Church, Stratford-upon-Avon, Warwickshire, UK, the same church in which Shakespeare was baptised.

Yes, although neither he nor anyone else seemed to be sure of how to spell it. But that was true of everyone--nobody knew how to spell anyone's name. We have settled on the spelling "Shakespeare" because that is the one found most often in his published works. The spelling "Shakespear" is also common: that's what's on his grant of arms. On his funerary monument it is spelled "Shakspeare"

That was the Djeser-Djeseru. We know it as The Mortuary Temple of Queen Hatshepsut.

A stele or stela is a stone or wooden slab, generally taller than it is wide, erected as a monument, often for funerary or commemorative purposes.

You should look at one of the contemporary portraits of Shakespeare (the Drousehout engraving or his monument in Stratford Church) to get this information.
