It was the year 1172 when Bishop Albert von Trient gave the Lords of Enn permission to build a castle above Montan. The noblemen were already in possession of Castelfeder, which at that time had already fallen into serious disrepair. This is how their new residence was created in a more protected place, which went hand in hand with the castle hat, i.e. the safeguarding of the Truden area. Count Meinhard II finally conquered the castle in the 13th century and drove out the lords of Enn, whose trace is lost in the course of history: the Counts of Tyrol took over.
In 1648 the castle, like other South Tyrolean castles, became the property of Pietro Zenobio, from whom the Tyrolean sovereign had taken out a loan. The Tyrolean nobility protested. But Enn Castle remained in the possession of the Venetian patrician family, whose descendants had the complex expanded in the neo-Gothic style in 1880. It is still owned by the family of Baron Rubin de Cervin-Albrizzi and cannot be visited: once a year, however, the Montan band gives its traditional palace concert in the inner courtyard, which is also open to the public.
