As trustees of the association it was decided to donate the funds held to Holbeach and East Elloe Hospital Trust in order that the work can be continued within the local area.
Holbeach Hospital manager Maxine Winch said she was extremely grateful for the generous donation and already has plans to put the money to good use.
She said: “Although the nursing association will no longer exist, the money they have raised over the years will still benefit the local community.
“The members should be very proud of the substantial amount donated to us; it will be used to help fund our expansion projects which seems a fitting legacy.
“On behalf of the trustees and those who use our service I would like to extend thanks for this extremely generous gift.”
