Missing possible POI
"Ballyknockan Quarries Heritage Museum"

Might be only on appointment with exhibitions solely during yearly festival.
no signage visible on streetlevel imagery, only that of its operator.

Also, there is supposedly
"restored crane which first worked in Ballyknockan in the 1850s"
