[1] After Baron Johann von Attinghausen's death around 1360, ownership passed to the Haslital Knight of Rudenz (by virtue of marriage).

The Knights of Rudenz were in the service of the Freiherr of Brienz-Ringgenberg and owned castles in Meiringen and Giswil before inheriting the tower at Flüelen.

The inheritance was disputed and Johann von Rudenz finally took possession of the castle in the 1370s.

As part of receiving the inheritance on 19 June 1365 he granted half the collected tolls to the Canton of Uri.

[2] After the death of Johann von Rudenz, the castle passed through a number of owners.

However, over the following centuries, they had to sell off parts of the land and the gardens were replaced with streets and buildings as Flüelen grew.
