Put negative in enlarger and adjust to the size of your final print. Place some thick card or an old print in place of your photographic paper. Then draw a pencil outline around the spire, cut out the spire and the rest of the print, then use it as a mask when you expose your final print. You may have to cut slightly inside the outline you have drawn to prevent a halo around the spire.
If the spire is fairly prominent on the final print use your hands and fingers (like making finger shadows on a wall) to mask.
Possibly contact some OHP film with the large format negative then paint photopaque(sp?) on that to produce a mask.
