I've been stumped at what is on the roof of the lodge at the main entrance to the cemetery in Tollemache road

is it
a weather vane?
an aerial for something?
a lighting rod?

Can't find any older pictures, but it looks like it was a weather vane to me?
Is that a bell tower?

"Office and Lodge to cemetery. 1862-4. By Lucy and Littler.
Coursed and squared rubble with Welsh slate roof. 1- and 2
storeys, asymmetrically-planned in picturesque gothic style. 3
bays to south elevation with central tower over entrance
porch. Moulded archway with shafts and hood mould. Wide
chamfered angles to tower above with gable in each face, with
heavy foliate bases to short shafts each side of Birkenhead
arms, then tall timber fleche with trefoiled niches and
wrought-iron finial. Window and dormer in roof over to right.
Office to left with stepped 3-light foiled window in expressed
gable, and segmental bay window with half-conical roof and
paired transomed lights in end gable."

Looks like it has a lightening strap also.

The owner of the lodge is on the Flaybrick Memorial Gardens and Lodge History facebook group https://www.facebook.com/groups/876102829516940 but it is a private group so you would have to join the group.

No idea on the ornate metal spire, it may have been purely decorative or might have been a lighting conductor, the spire itself is wooden with lead sheet covering. The modern rod strapped to it appears to be an antenna whose cable is broken lower down.

Must be during construction
