The farm

Thiemanns Farm is a half-timbered farm house with a well and bake house in Bierde near Petershagen in East-Westphalia. The classic four-post Westphalian farm house (also known as Low German house) was built in 1875 by Friedrich Aumann and inhabited until the 60s. The farm is an excellently preserved testimony to peasant building, living and farming in the late 19th century.

The farm is known as ‘Thiemanns Hof’ (Hof = farm). So far, we haven’t been able to find out much about the origin of the name.

The building is a protected monument and in recent years it has carefully been renovated according to modern building standards.
