Here is a grid overlay. The camera was levelled on a tripod and seems to be about right ( the fence on the LH side)
Here is a previous shot taken with a 24mm PC. The tower kind of leans and is curved, due to compaction of the mortar on one side.
This is pretty common with church towers in this part of the world. Vendaso is on the side of a mountain and earth movement and earthquake have distorted the structure. Take a look at the walls on the extreme sides.
The Laowa 15mm PC lens is very nicely corrected and might show some stretching on the edges.
