The White City on the Seashore: the Danish National Exhibition - Hall of Electricity, 1909. The Hall Of Electricity With, On The Right, The Machine Hall With Giant Anvils At The Entrance. Aarhus, the second largest town in Denmark, boasts with good reason of its White City on the Seashore, the Danish National Exhibition that is being held within it, and that will be an attraction until September. The grounds of the exhibition and the buildings are alone well worth seeing, but all is by no means outward show; the exhibits are as interesting as they are varied. Apart from the exhibition, Aarhus itself is a centre that no visitor to Denmark ought to miss. It is a cathedral town, and its bishopric was founded, in the tenth century, by Otto I..
