(Swedish: Gripenbergs slott)
is a wooden castle near Tranås in Småland, Sweden.
It is considered to be the biggest wooden castle in Sweden
and one of the oldest that are still remaining today as well.
Gripenberg Castle was built in 1663
as a huntig seat for the field marshal Carl Gustaf Wrangel.
Its architect is unknown,
but there is some reason to believe,
that it might have been Nicodemus Tessin the Elder.
It is assumed that the castle's name is derived
from the name of
Wrangel's mother Margareta Grip
and that Wrangel might have chosen it to commemorate her.
By the end of the 17th century
the castle was bought by Samuel von Söderling
and remained in the possession of his family until today.
