The origins of the house date back to 1382 as it was carved into an old stone wall.
The stone ground floor was only bricked up a few decades later - in the 15th century. The half-timbered structure dates from the 16th century. As history shows, the Swedes were also in Marktbreit during the 30-year war (1618 - 1648) and the Swedish soldiers were allegedly housed here at the time.In 1646, a certain Ernst Sartorius married into what was then still called the "Groehof" and took the "hospitality" (licence to run an inn) from an opposite "Ausspanns" (a formerly common name for an inn or a tavern on old trade routes that offered space for the accommodation of horses and carriages for travelers) with him along with its name "Zum goldenen Löwen". The house later went down in town history under this name Ernst Sartorius was an economically very influential man. In addition to the inn, he ran a wine and grain trade and was one of the highest taxpayers in the town in 1656. After 1661 he operated a large shipping business with a few ships between Marktbreit and Frankfurt. As a major supplier in the Dutch War (1672 - 79), he was stuck with high demands due to the insolvency of the imperial treasury, and his business collapsed. The Golden Lion went to a Johann Veeth from Dettelbach for 1000 Rhenish Thaler, who took over the customs administration in Marktbreit in 1684.
