I'm sorry.
This ia a yearly halloween attraction, which is open a couple days around halloween.
It is a private project by an event technician, but it's open to the public and free for entry. They are using animatronic puppets and build a scare maze using lots of light, fog, sound and fire effects.

I will ask the operators about the exact opening dates and add this data to the feature. 
On google maps there are a few pictures and videos showing the attraction.
