The East India House is an impressive building built to house the Swedish branch of the international trade company of the 18th century. Today, it houses the history museum and apart from Göteborg history, including finds from the East India ship that sank, there are exhibitions on vikings, Asian cultures and much more. It also has a nice cafe and is child friendly.
Just off Gustav Adolfsplatsen you will find the Stadsmuseum.
In it there is the whole history of Gothenburg and its nearby surroundings displayed. From prehistoric to modern day.
One of the nice things to see is a vikingship and treasures they found from Middle ages. The Middle age department was setup like a town where you could walk through and see things in a more natural surrounding.
Another thing to see was a movie about the building of the first bridge over the Gotha.
This building, formerly a warehouse and offices for the East India company, details the history of Gýteborg. The history of the city is unique, as its beginnings were a bit, shall we say, cosmopolitan, with town fathers from Scotland, Denmark, Holland, and I believe, France.
The museum is located in an old East India Company House from the 1750s. The exhibitions are about the history and culture of Göteborg.
