Haga belongs to the old city of Gothenburg, said to be built in the 17th century, the ground of the old city is pebbles. It's not too early to go to HAGA on Sunday, because many stores don't open until 11:00, so when we go there, we can only look at the merchandise in the window. In fact, there are Skansen Kronan and Oscar Fredrik Church near Haga, which can be visited together.
