Skokloster Castle is a Baroque castle built between 1654 and 1676 by Carl Gustaf Wrangel, located on a peninsula of Lake Mälaren between Stockholm and Uppsala. It became a state museum in the 1970s and displays collections of paintings, furniture, textiles and tableware as well as books and weapons that amount to 20,000 items.  It also has the dubious distinction of being unfinished.  The unused postcard is aging and has some staining on the reverse, but at the same time, recent photos make it look like trees now take up much of the space where the card shows none.  We can’t verify that.  Grade: 2
