Recess of building for wall paintings (8)
I believe the answer is:
frescoes
'wall paintings' is the definition.
(fresco is a kind of wall painting)
'recess of building' is the wordplay.
'building' indicates anagramming the letters.
'recess'+'of'='recessof'
'recessof' anagrammed gives 'FRESCOES'.
'for' acts as a link.
(Other definitions for frescoes that I've seen before include "Wall paintings" , "Paintings on wet plaster" .)
