Centre licensed to hold old artefact (5)
I believe the answer is:
relic
'old artefact' is the definition.
'relic' can be an answer for 'artefact' (I've seen this before). I'm unsure of the 'old' bit.
'centre licensed to hold' is the wordplay.
'to hold' indicates a hidden word (I've seen 'holds' mean this).
'RELIC' can be found hidden inside 'centre licensed'.
Can you help me to learn more?
(Other definitions for relic that I've seen before include "Surviving artefact" , "precious object" , "Fossil" , "Something of antiquity, religious or sentimental" , "Revered object" .)
