Reinsberg, Cultural heritage monument in Eppan an der Weinstraße, Italy.

Reinsberg is a stone structure set amid vineyards in South Tyrol, featuring architectural elements typical of the regional noble estates of the area. The building preserves traditional South Tyrolean construction methods and design details that reflect the building practices of past centuries.

This property developed as a noble residence and served as a family seat across multiple generations, with its architecture reflecting the evolution of regional building styles. Its official designation as a cultural monument documents its importance in the architectural history of South Tyrol.

The estate's name comes from the old farm name Pitzol or Pozal, recorded from 1194 to 1239 with a vassal family of the Counts of Eppan. From 1559 the Grustner family bore a coat of arms, confirmed with a noble title by Emperor Ferdinand II in Vienna on 16 March 1624, when the seat at Pizal was raised to a free estate. The family called itself Grustner von Grustdorf und Reinsperg from 1750 and died out in 1834.

Reinsberg stands in the wine-growing area around Eppan an der Weinstraße, in the district of Pizal, and is a protected monument since 6 July 1951. It is a private estate with two building wings and the Holy Cross chapel, so visits are not open to the public; the round-arched gate with its coat of arms stone of 1661 is best seen from the passing path.

The chapel was built from 1676 to 1677 as an octagon with a dome and lantern, replacing nothing of the earlier medieval tower house that preceded the estate. The round-arched gate below carries a heraldic stone dated 1661, the year the Grustner family extended the building.
