The Finnish: tursaansydän or Finnish: tursan sydän[1], also called Finnish: mursunsydän, is an ancient symbol used in Northern Europe. The symbol originates from prehistoric times.The Finnish: tursaansydän was believed to bring good luck and protect from curses, and was used as a decorative motif on wooden furniture and buildings in Finland. During the 18th century the simple swastika became more popular in Finnish wood decoration than the more complex Finnish: tursaansydän.
Author Ilmari Kianto used the tursaansydän as his logo. Kianto had found a tursaansydän carved into his childhood home's granary's door in Suomussalmi.[2]
The Slavic Union used the tursaansydän in their logo, before being banned in 2010.
The Finnish Alliance approved of the tursaansydän as their symbol in 1998.[3]
