Man turning up at an ancient city in Belgium (5)

I believe the answer is:

namur

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

'belgium' is the definition.
I know nothing about this answer so I can't tell whether this works.

'man turning up at an ancient city' is the wordplay.
'turning up' says the letters should be written backwards.
'at' says to put letters next to each other.
'an ancient city' becomes 'ur' (ancient Sumerian city state).
'man' backwards is 'nam'.
'nam'+'ur'='NAMUR'

'in' is the link.

Can you help me to learn more?

(Another definition for namur that I've seen is " Belgian city and province".)

I've seen this clue in the Evening Standard.
