Around 40 castles and palaces bear witness to the eventful history of the cultural region Venosta Valley. Some of them are in ruins and vestiges of buildings remain, yet others, such as the Schlandersburg Castle, have been preserved from decay by ongoing use and restoration.

In Silandro/Schlanders and Lasa/Laas, there are impressive monuments of bygone eras. The Schlandersberg Castle, ancestral home of the Lords of Schlandersberg, has been dominating the Venosta Valley capital since the 13th century. The similar-sounding Schlandersburg Castle however, is a magnificent Renaissance building with two-storey loggia courtyard, crenellated gables and an oriel tower.

In the marble village of Lasa, there are especially old farmsteads, studios and manor houses with medieval foundations, such as the Eyrsburg Castle, also Moosburg, from the year 1497 – a homestead with a square tower, swallowtail battlements and a high arched entrance in Oris/Eyrs. The Tschenglsburg Castle in Cengles/Tschengls near Lasa is also impressive.
