The Wengia Solodorensis is the oldest Studentenverbindung (German: [ʃtuˈdɛntn̩.fɛɐ̯ˌbɪndʊŋ]; also referred as "Verbindung"; translated as student society or fraternity) at the Kantonsschule Solothurn, the cantonal college of higher academic education.

The purpose of the society, true to its motto Patria, Amicitia, Scientia ("Fatherland, Friendship, Science") is set out in their charter as follows: "Der Zweck der Wengia ist es, das wissenschaftliche Interesse ihrer Mitglieder zu fördern.

At the beginning of the 1880s there were already student groups at the Kantonsschule Solothurn as offshoots of the university corporations “Helvetia” and “Zofingia”.

In the summer of 1884 several students came together under the leadership of Bernhard Wyss and Leo Weltner with the aim of founding a new society.

[3] The first president was Adolf Meyer v/o Storch, who passed away while he was still active, Leo Weltner v/o Streck acted as first Fux-Major.

With school and fraternity life restricted, members showed great interest in the course of war and put themselves at the service of the Spiritual national defence.

The motto Patria and Scientia ("Fatherland, “Science") is upheld through lectures on political or scientific topics at regular meetings and study trips.

The motto Amicitia (“Friendship”) finds its expression in the social occasions of the society such as regular tables, Kneipen, Kommersen (both ceremonial drinking and singing sessions), balls, study trips, etc.
