Architectural feature in Kosovo location (5)

I believe the answer is:

ovolo

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

'architectural feature' is the definition.
The definition suggests a singular noun which matches the answer.

'in kosovo location' is the wordplay.
'in' indicates a hidden word.
'OVOLO' is hidden in the letters of 'kosovo location'.

Can you help me to learn more?

(Other definitions for ovolo that I've seen before include "Thumb" , "decorative strip" , "Rounded architectural moulding" , "Convex moulding" .)
