In the Middle Ages, the "High Cathedral Church" in Trier had many possessions. The Benedictine Abbey of Mettlach with its farm near the "All Saints' Chapel" in the former Müstert occupied a special position. In 1219, it transferred the right of patronage in Piesport St Michael to the Trier cathedral chapter with a third of the "tithes". The estate grew through donations and the purchase of vineyards and land. A stately "Domhof" was created. In 1721, the estate reached an impressive size and was labelled "Domhofs Gehäus" on a site plan. It is an example of generous Baroque architecture.
The Piesport vineyards "Domherr" and "Dompichter" as well as the street name "Am Domhof" are still reminders of the estate of the Trier cathedral chapter. In the course of secularisation under Napoleon, the nationalisation of all ecclesiastical property, the "Domhof" was auctioned off in 1805 together with the farmhouse, wine press and vineyards for 222 thalers. In later years, the building was owned by the Imperial Counts of Kesselstatt. Their coat of arms adorns the front of the building.
