Vandals attacked the new Luxford Field play area in Uckfield within 24 hours of its opening on Saturday (September 19).
Uckfield Town Council said a difficult-to-remove paint was sprayed onto equipment and grounds staff had to remove the graffiti on Monday morning.
A spokesperson said: “It is extremely disappointing to have to deal with this sort of vandalism and particularly galling when it has happened at the newly refurbished and opened Luxford Play Area. It is also frustrating having to divert our grounds staff from their usual duties in order to deal with it.”
The castle-themed play area cost £130,000 to build. The money saved up over several years to pay for the work.
