Built in 1560 by Valentin Fries, it is the Mieg family, owners of the premises from 1675 to 1840, who gave it its name. It owes its present appearance to Mathieu Mieg who, in 1799, decorated the façade with murals of his composition evoking the Swiss hero Arnold de Winkelried. The Mieg House is the largest of the houses surrounding the Place de la Réunion.
