Councillors in Tallaght are opposing Scientology plans to build a playground in Firhouse.
The church has applied for planning permission to add it to its recently opened Victory Centre.
Child protection concerns have been raised because of its proximity to schools and request for CCTV.
The application by Julie Lind says it would be a focal point for the community. It includes proposals for "a flat roofed infill structure to form a new internal lobby area... the erection of a timber clad fence... the erection of playground equipment with perimeter fence and hedging installed to a height of 1.3m; the erection of 2 CCTV camera poles 4.5m high"
Local Fine Gael councillor Brian Lawlor outlines why people are opposed.
"It's a change of planning use for that particular site. That site was a place of worship for their own followers. The park there is a diversity park so people are against lights and cameras and all that."
