I looked in the Genteam gazetteer, and there is no place named Spuz or Spruz. There is or was however, a place named Spiz, in the Tirol, which today is in the Italian Tirol. It is in the current parish of Sagron Mis, and former parish was Fiera de Primiero.
I am not sure if this is the right place, but it is only one I could find that seemed to. I tried replacing the “u” with every other vowel, and with wildcards, nothing else fit.

Fiera di Primiero (La Fiera in local dialect) was a comune(municipality) in Trentino in the northern Italian region Trentino-Alto Adige/Südtirol, located about 60 kilometres (37 mi) east of Trento. It was merged with Siror, Tonadico and Transacqua on January 1, 2016, to form a new municipality, Primiero San Martino di Castrozza.[3]
With an area of 0.15 square kilometres (0.058 sq mi), Fiera di Primiero was one of the smallest municipalities in land area in Italy.[2]
