Pontremoli tower sundial - white Carrara marble

The sundial, if correctly mounted with the gnomon on the South and positioned in the original area from which the design was detected, will provide inaccurate indications but still close to the temporal reality.
Recall that the sundial does not calculate the summer time and however we want to specify that the montage of this object is related purely to an aesthetic-historical factor. If you want a precise and reliable measuring instrument, we do not recommend the purchase.
