Sandhammaren lighthouse situated on the southeast corner of the
Skåne provins, was the first lighthouse built in steel by Heidenstam in 1861.
An unusual solution at the time; earlier lights was always built in stone.
This lighthouse location was originally eqipped with a twin lighthouse for
easier recognition. The development of new techniques,
(rotating fresnel lenses) that was able to give every lighthouse its own
light-character made the twinlight unnecessary, the upper light was demounted
in 1894, and moved to a new location near Piteå in northern Sweden to be relit
in 1904 as Rönnskär lighthouse.
