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

'french town' is the definition.
'lourdes' can be an answer for 'town' (I've seen this before). I am unsure of the 'french' bit.

Can you help me to learn more?

(Other definitions for lourdes that I've seen before include "Place of pilgrimage in the French Pyrenees" , "pilgrims' destination" , "SW France pilgrimage site" , "Shrine in SW France" , "It offers hope to the sick" .)

I've seen this clue in The Times.
