Thürnen commune (Basel Land half canton, Switzerland)

Translated from the German blazon:

"Since 1944. In a golden field on a three-mountain a black tower with a ringwall, flanked by two gates of entry. Cause of the design of a new coat of arms was the oral tradition, that the place name meant: "at the towers". For this design a reconstruction of an early medieval castle of refuge was used on the edge of the castle with a tower and a double gate. The colors remind of the former belonging to the region of Homburg"
