At about the same time, the castle came to be known as Jörgenberg from the name of the nearby early medieval fortified Church of St George.

[3] In 1734 the municipality of Waltensburg, which at that time included Rueun, Siat, Pigniu, Andiast and Schlans, bought the last rights of the Jörgenberg fief.

A procession from Roman Catholic Andiast through Waltensburg toward Rueun in 1682 started the Fahnenkrieg (Flag War) in the valley.

However, starting in 1961 many of the small farms began to combine into a few larger operations which led to the emigration of many farmers to Ilanz, Domat/Ems and Chur.

The blazon of the municipal coat of arms is Argent St. George armoured Azure caped Gules and Or and haloed and with lance of the last riding a Horse Sable harnessed of the third killing a Dragon Vert.

[4] The coat of arms features St. George who is the patron saint of the church and who the castle, Burg Jörgenberg, is named after.

Of the rest of the land, 1.5% is settled (buildings or roads) and the remainder (39.9%) is non-productive (rivers, glaciers or mountains).
