Vārenbrock manor (German: Wahrenbrock) is located in Vārnava, Jēkabpils Municipality, 3 km from Lake Piksteres.
The original wooden building of the Vārenbrock manor house was built in the first half of the 18th century, but was significantly rebuilt in later centuries. The biggest reconstructions took place at the end of the 18th century and the first half of the 19th century, when the wooden building was rebuilt in the classicist style.
The building has been a cultural monument of regional importance since 1998.
In 2022, extensive renovation works of the manor building were started.
