As the last days of August approach, many of us are searching for ways to eke out our summer before packing away the shorts and sunglasses. One tried and tested way is by heading for a city in southern Europe – somewhere you can combine culture and sightseeing with the possibility of a dip in the sea, perhaps, or an al fresco meal. If you’ve got a favourite city break destination that’s perfect for late summer or autumn sunshine, we’d love to hear about it. And please share details of great places to stay, walk and eat, too.

If you have a relevant photo, do send it in – but it’s your words that will be judged for the competition.
