Weinfelden is an old town, which was known during Roman times as Quivelda (Winis Feld).

Weinfelden is mostly known throughout Switzerland for its hockey team, HC Thurgau which is currently playing in the Swiss League.

In 1798, Paul Reinhart and his committee led the area to freedom from the domination of the Eidgenossen.

In 1803, Thurgau became an independent canton, through the mediation of Napoleon, with Frauenfeld as capital.

In 1830, Thomas Bornhauser spoke to a large crowd in Weinfelden, demanding a liberal constitution for the canton.

Portraits of both Paul Reinhart and Thomas Bornhauser hang in the Rathaus.
