Hundreds flocked to Matlock to pledge their support for Darley Birth Centre.
Residents, visitors and shoppers signed a petition against NHS proposals to close the unit in Darley Dale during a two-day campaign in the town centre.
The event was led by Matlock Hospitals League of Friends.
Chairman Diana Dakin, said: “We had an absolutely brilliant response.
“We had people coming across the road when they saw the banners and one lady pulled up in her car, jumped out, signed the petition and took a questionnaire.”
In May, the NHS began reviewing the future of the midwife-run centre.
Health bosses say running Darley is expensive and that only 100 women a year use it.
But campaigners claim the centre is worth the money and provides an invaluable service to the community.
Supporters spent Friday and Saturday at the entrance to Hall Leys Park, gathering signatures.
Diana said: “One thing that came out was the fact the centre hadn’t been promoted and mums didn’t know they could go there.”
Families will be able to have their say on the future of Darley at a public meeting at the Whitworth Centre, in Darley Dale, on Monday, September 26, from 7.30pm.
This is your last chance to sign our Don’t Ditch Darley petition.
We will be handing over the hundreds of coupons and signatures that we have been gathering, at the event – so make sure you have your say!
