Home of Bosch's "The Garden of Earthly Delights” (5)
I believe the answer is:
prado
'home of bosch's the garden of earthly delights' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for prado that I've seen before include "picture-house" , "gallery for paintings" , "exhibits here?" , "gallery abroad" , "foreign gallery" .)
