House of Perkunas in Kaunas is one of the most original and archaic Gothic secular buildings in Lithuania.
Originally built by Hanseatic merchants in the late 15th century,
it was sold in the 16th century to Jesuits,
who had established a chapel there in 1643.
The ruined house was rebuilt in the 19th century
and served as a school and a theatre,
which was attended by Adam Mickiewicz.
In the end of the 19th century it was renamed to "House of Perkunas",
when a figure, interpreted by romantic historians of that time,
as a figure of Perkunas god,
was found in one of its walls.
Today, House of Perkunas belongs to Jesuits again and hosts a museum of Adam Mickiewicz.
