A petition to save Lincoln’s Lawn complex has been launched online.
The complex is back up for sale for £1 million.
And chartered surveyors Hodgson Elkington have been instructed by City of Lincoln Council, the site’s owners, to market the Grade II* listed building in Union Road.
The council's previously rejected businessman Jonathan Pass's £1 million bid, which he offered to double, while a subsequent tender process failed.
The petition has been signed by 43 people so far and runs from April 5 until September 5.
Why the petition has been started is in a statement on the petition’s page which says:
“The Lawn is an iconic complex of buildings where new and cutting-edge methods were used to treat mental health patients from the 1820s.
"The Lincoln Castle Revealed project due for completion in 2015 will mean the Lawn could have renewed use as a tourist visitor centre/retail centre for craft businesses.
"The planned sale of the Lawn would be a major loss to the people of Lincoln and district.”
Hodgson Elkington will be marketing the property with a guide price of £1 million.
But a successful bid will not depend solely on price as the council is keen to see a viable and sustainable scheme for the building which will not only work for the developer but also for the city of Lincoln.
The Lawn was originally developed from 1819 as a purpose-built hospital for pioneering treatment and rehabilitation before closing in 1985.
The council bought the property from The Secretary of State for Social Services in 1986 and opened it four years later as a multi-purpose venue following extensive refurbishment.
