NHS bosses are keeping quiet about names of bidders for the former Welland Hospital site in Roman Bank, Spalding.
The hospital was finally demolished a few weeks ago after the building was wrecked by vandals and arsonists.
United Lincolnshire NHS Trust spokesman Rebecca Derbyshire said: “I have been told the site has been cleared and the security fence has been installed around it, but unfortunately we can’t comment on the marketing of the site so I can’t tell you about any bidders.”
