The House of Perkūnas is a fine example of late Gothic, also called Flamboyant ("flaming"). It was built in the 15th century by merchants of the Hansa, a Union of free cities of the German Empire. The house consists of two buildings, one of which served as a warehouse for merchants and was destroyed in the 18th century. The building that we can see now, was an office warehouse, according to historians. It does not have a kitchen, but there is a basement. It is assumed that valuable items were stored in it.

The layout of the house is very interesting: both floors are separated by two capital walls, which form six different rooms. It is noteworthy that in the 17th and 18th centuries, the house was repeatedly redeveloped and restored, but the exterior part, made in the Gothic style, was intact and beautiful has preserved its appearance to this day.

The facade patterns abound with details and perfection of lines typical for the Gothic style. At the same time, the house seems quite powerful and squat, despite the upward-pointing lines and decorative turrets. They are a kind of decoration there. Relief arches, intertwining with each other as if to say: "Look, man made us like this, he wanted us to be like this and it's beautiful!" Between the ornate brick reliefs, there are endless small niches and windows. They are tiny, but perfectly fit into the overall style of the building and emphasize its beauty. Even the roof of the house of Perkunas is still lined with ancient maroon tiles.

After the end of the First World War, the house became owned by the Jesuits. The Jesuit gymnasium began to be located there. In addition to educational institutions, the building now houses an exhibition dedicated to the Lithuanian poet Adam Mickiewicz, who lived in Kaunas for several years and became a symbol of Lithuanian poetry.

The Нouse of Perkūnas can be visited by anyone on weekdays during the working hours. Sometimes concerts and other events are held there on weekends.
