炉渣堆

Escorial \Es*co"ri*al\, prop. n. [Prop. Sp. escorial, i. e., a
hill or heap of rubbish, earth, and stones brought out of a
mine, fr. escoria dross of metal, L. scoria, fr. Gr. ?. Cf.
{Scoria}.]
A palace and mausoleum of the kings of Spain, being a vast
and wonderful structure about twenty-five miles northwest of
Madrid; called also {escurial}. It was erected in 1563-1584
and contains a monastery.
[1913 Webster +PJC]

Note: The ground plan is said to be in the form of a
gridiron, the structure being designed in honor of St.
Lawrence, who suffered martyrdom by being broiled on a
gridiron; but the resemblance is very slight. It is
nearly square, inclosing several courts, and has a
projecting mass which stands for the handle.
