Rentamt, Heritage monument in Roßla, Germany

Rentamt is a two-storey building at Helmestraße 3, 3a in Roßla, west of Schloss Roßla. Its ground floor is masonry, while the upper storey is exposed half-timbering with a richly profiled sill. A stair turret dated 1683 stands on the courtyard side, and the gate entrance is spanned by a round arch beside a seated-niche portal. A lower, plain service wing runs south from the southeast corner, giving the complex an L-shaped plan.

The site held one of three knight's estates in Roßla, whose cellar survives beneath the present house; a fire destroyed Roßla and the estate in 1656, and the two-storey building rose as a rebuild, though some sources date it to 1586 or 1600, with alterations in 1683. In 1720 Count Jost Christian zu Stolberg-Roßla bought the former Amthor estate and joined it to Schloss Roßla by a covered bridge; the ground floor then housed the Renterei session room, chancellery, forestry office and police council. The community owned it until 1996, when it was still the municipal administration's seat; sold at auction in 2013, it is now privately owned and being gradually restored.

The name refers to its former role as an office for managing rent payments and administrative duties. The building still displays the solid construction and proportions typical of public administrative structures from that period.

The building is located in the town center of Roßla and is walkable from local transport connections. It is best viewed from outside to appreciate the architecture and construction details, as it is a protected monument.

In the southwest side wing the counts kept a library of roughly 30,000 volumes. The building also housed the chancellery, the forestry administration and the police council's office, and Count Jost Christian had it linked to Schloss Roßla by a covered bridge in 1720.
