Societetsskolan
Societetsskolan i Göteborg för döttrar (The Society School for Daughters in Gotheburg) or simply Societetsskolan (The Society School), also referred to as Brödraförsamlingens flickskola i Göteborg (The Girls' School of the Unity of the Brethren in Gothenburg) and Evangeliska Brödraförsamlingens flickskola i Göteborg (The Girls' School of the Unity of the Evangelical Brethren in Gothenburg), or, finally, as Salsskolan (The Hall School), was a Swedish girls' school managed by the congregation of the Moravian Church in Gothenburg from 1786 until 1857.
It is referred to as the first girls' school in Sweden, because it was the first institution to provide serious academic- and secondary education to females.
