Heights in Heligoland, nominally? (5)

I believe the answer is:

golan

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

'heights' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'in heligoland nominally?' is the wordplay.
'in' indicates a hidden word.
'GOLAN' is hidden in the letters of 'heligoland nominally'.

Can you help me to learn more?

(Other definitions for golan that I've seen before include "Syrian heights occupied by Israel" , "disputed Israeli/Syrian Heights" .)

I've seen this clue in the Evening Standard.
