I believe the answer is:

cawdor

I'm a little stuck... Click here to teach me more about this clue!

'highland castle' is the definition.
(Cawdor Castle)

'central part opening we hear?' is the wordplay.
I cannot really understand how this works, but
'central' could be 'c' (common abbreviation in various government acronyms) and 'c' is present in the answer.
'part' could be 'do' (do is a kind of part) and 'do' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Another definition for cawdor that I've seen is " Scottish castle".)

I've seen this clue in The Guardian.
