Gut Landruhe, Cultural heritage villa in Horn-Lehe, Germany

Gut Landruhe is a single-storey Neoclassical manor house with a hipped roof, 28.70 m long and 13.20 m wide, its nine-window front centred on a two-storey risalit with four Ionic pilasters and a triangular pediment. The estate at Am Rüten 2–4 also holds a small Tudor-style orangery of around 1840, a thatched Lower Saxon Meierhof, a double gate, a cast-iron bridge and a Thalia sculpture.

A manor at this site was first recorded in the 13th century as Gut zum Schorf, a Geerengut belonging to Lilienthal Monastery. Around 1660 the Barkey family built a timber-framed house; in 1795 merchant and captain Carl Philipp Cassel bought the estate for 7,000 Reichstaler, had the old house demolished and commissioned architect Joachim Andreas Deetjen to build the present Neoclassical mansion, which he named "Ruhe auf dem Lande". The ensemble has been under Bremen monument protection since 1973.

The name Landruhe ("rest in the countryside") was given by Captain Carl Philipp Cassel, who built the classical manor around 1795. Around 1840 the Kulenkampff family added the small Tudor-style orangery, heated by pipes beneath the windows, and in summer Emmy Kulenkampff taught Sunday-school children from Rockwinkel and Oberneuland there. The Thalia sculpture is said to portray Cassel's lover, an actress at Bremen's city theatre.

Gut Landruhe stands at Am Rüten 2–4 in Lehesterdeich, on the Horn-Lehe side of the border with Oberneuland. The 33,630 m² Menke Park, named after the estate's last owners, has been open to the public since 1994; a tree-biography trail with 14 stations was laid out there in 2002. The manor house itself was converted into a conference venue in the late 1990s and is not a public museum.

The small orangery, built around 1840 in a historicising Tudor style, had a "Chinese heating" system with pipes beneath the windows. In summer Emmy Kulenkampff used it as a classroom for a Sunday school she set up for children from Rockwinkel and Oberneuland.
