Swedish officer arrested among large, imposing buildings (8)

I believe the answer is:

edifices

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

'buildings' is the definition.
('edifice' can be a synonym of 'building')

I can't explain the rest of the clue.

(Other definitions for edifices that I've seen before include "Buildings, structures" , "Large or imposing buildings" , "De-ices if found in buildings" .)

I've seen this clue in The Irish Times.
