Old Frisian longhouses were, as the name indicates, long-bodied houses which can be found in the Dutch province Friesland.
There are a variety of types, but most have vanished during time.
The only remaining longhouse is located in the Dutch village Wartena.
One of the oldest reminding of this type of residence comes from an undated writing from around 1850 from J.H.
Halbertsma made an untidy schematic drawing that shows the lines of the outer walls of a longhouse.
