The public meeting organised by Plaid Cymru in the Lager Club from 7pm on Wednesday will hear speakers outline how the local council and Welsh Government has helped "wreck" Wrexham.
Elaine Guntrip-Thomas from the Save our Heritage group campaigning to save the Groves from demoltion will be among the speakers and she will be joined by Pete Garrett from the Splash Magic campaign to keep Plas Madoc Leisure Centre open.
Local historian and writer Phil Phillips will also outline some of the heritage lost locally and Cllr Marc Jones will speak on the Local Development Plan and the council's intention to build two new villages on greenfield sites.
Concerns about the future of our local health services in terms of GP services, local community hospitals and pressures on Wrexham Maelor hospital will also be raised.
Carrie Harper, Plaid Cymru's candidate in May's election, said:
"There's a wide range of concerns about the way things are going in Wrexham at present.Doors open at 7pm and the meeting starts soon after.
"Important decisions are being made without consultation with the wider public, in fact against the wishes of the public. Our heritage, important buildings and our green fields are at risk because we have a council and government that are unwilling to listen to local people and seem to have an agenda of their own.
"This is intended to be a positive meeting because we've seen, for example with Plas Madoc, how a community can fight back and win against all the odds. So we take our inspiration from there and we're determined not to let the powers-that-be wreck Wrexham with their policies."
