Not all stone is the same

Holler Porfidi is a successful company in the sector of porphyry manufacture. In 1978, Gino Holler wanted to produce porphyry products to meet the most demanding requirements. To this end therefore all his products were produced exclusively from material from his own quarry in Albiano (TN). In the course of time, Holler Porfidi acquired additional quarries in Laives/Leifers (BZ) and in Puerto Madrin (Argentina); so that they could offer their customers an ever wider choice of porphyry products they made themselves.
