The pro­duc­tion of oil at Olje­ko­ken in Gös­sä­ter was established in 1893.

But it pro­ved too expen­si­ve to extract oil from alum sha­le. The oil was use­less as lubri­cant but could be used to impreg­na­te rail­way slee­pers. After only a few years, fil­led with pro­blems and set­backs, pro­duc­tion cea­sed in 1897. At that point, around 100 tons of poor-qua­li­ty oil had been extrac­ted. Not­hing remains today of the­se facto­ry buil­dings. The only tra­ce of this era is a dwel­ling house, known local­ly as Olje­ko­ken (“the Oil Boiler”).

The first boiling house was situ­a­ted below the quar­ry (the buil­ding with the birch tree in the chim­ney). Below the hill is a lar­ge area with remains from the oil sha­le quar­ry­ing. The­re are also plen­ty of kiln foundations.
