St Mary's has been quietly running a charity since 1574. Details including governance can be found here
The charity's sole aim is in providing funds for the maintenance of St Mary's church. The endowment is invested into the COIF Fund (managed by CCLA) and pays a dividend. The charity incurs no running or indeed administrative costs.
The charity would be pleased to receive more capital to be able to invest, clearly the funds will provide for regular income for the church in perpetuity to provide some element of stability to help preserve the building.
Do please consider this, perhaps a legacy or indeed via Amazon purchases.
