The above is a - pretty poor - translation of ABerrant's link, and a more accurate translation - in a nutshell - would be:
"At this beautiful spot above Partenkirchen, there stood a small chapel until its demolition in 1803. The crucifix was then erected in 1924 at the site of the disused Sebastian graveyard and has been refurbished three times since (1939, 1965, 2003).
Every year, on Whit Monday, there is a service of celebration at the site."
