Wall painting survives, higher (4,6)

I believe the answer is:

last supper

'wall painting' is the definition.
(Da Vinci painted The Last Supper on a wall)

'survives higher' is the wordplay.
'survives' becomes 'lasts' ('last' can be a synonym of 'survive').
'higher' becomes 'upper' (higher up).
'lasts'+'upper'='LAST SUPPER'
