Eltzhof, Estate and architectural heritage monument in Wahn, Germany.

Eltzhof is an estate in Wahn, North Rhine-Westphalia, made up of several buildings showing typical regional construction methods. The complex includes a main residence, farm buildings, and storage structures arranged around a central courtyard.

First documented in 1735 as the Paulshof, the estate passed from Maximilian Damian Henrich Freiherr Schall von Bell to Lucia Marx and her son Johann Halbach. The Heereman von Zuydtwyck family owned it from the late 18th century, and through marriage it came to the von Eltz family in 1835, when it took the name Eltzhof. After World War II the Cologne Chamber of Agriculture leased it as a teaching and research farm until 2004.

The name Eltzhof dates from 1835, when the farm passed to the von Eltz family by marriage; before that it was called Paulshof. Today the former workers' houses hold a brewery tavern with a beer garden run by the Kölner Dom-Brauerei, and the cobbled inner courtyard is used for open-air events.

The enclosed courtyard with its historic cobblestones is used for open-air events, and the former farmworkers' rooms now hold a brewery restaurant with beer garden. A theatre seating about 450 people occupies part of the complex. The buildings stand directly beside the avenue separating them from the Schloss Wahn gardens, so the two can be visited together.

The courtyard keeps its historic cobblestone paving, and open-air events of all kinds are held on it. The site also holds a theatre seating about 450 people, built into the former estate buildings after 2004.
