Schloss Lieser, Historicist castle in Lieser, Germany

Schloss Lieser is an Art Nouveau castle in Bernkastel-Kues along the Moselle River with a main pavilion spanning four floors and a prominent tower at the front. The structure combines Art Nouveau features with neo-renaissance-inspired elements and includes wine cellars and storage spaces on the ground floor that are elevated to protect against flooding from the nearby river.

The older wing was built from 1884 to 1887 to designs by Frankfurt architect Heinrich Theodor Schmidt, on the site of a 1710 court house of a church estate. It was the family seat of gas industrialist Eduard Puricelli, whose daughter Maria inherited it in 1895 and married Clemens Freiherr von Schorlemer-Lieser, after whom the castle is named. Around 1904–1906 the building was enlarged with a smaller Art Nouveau wing; Kaiser Wilhelm II visited in 1906, 1911 and 1913.

The castle's name comes from Clemens Freiherr von Schorlemer-Lieser, who married Eduard Puricelli's daughter Maria in 1880; she inherited the estate in 1895. The chapel on the first floor has wall paintings by Karl Julius Grätz and glass paintings by Binsfeld and Janssen, with a mosaic floor designed by the architect and made in Mettlach. A statue of the owner's wife in old German costume, keys and purse in hand, stands as an allegory.

Access to the grounds is possible, but some areas may be restricted, so it helps to check the current visiting situation beforehand. The castle sits directly on the Moselle and is easily reached from the town center of Bernkastel-Kues.

The stairwell between eight large pilasters carries painted landscapes and architectural motifs of the Mosel region by Karl Julius Grätz, and its lead-glazed window holds four painted medallions by Binsfeld and Janssen of Trier. The staircase itself is built of Trier sandstone with wrought-iron, partly gilded railings.
