Read it through once

The next feature that strikes one is the spaciousness, the roominess of the city. There is no other city, in any country, whose streets are so generally wide. Berlin is not merely _a_ city of wide streets, it is _the_ city of wide streets. As a wide-street city it has never had its equal, in any age of the world. ‘Unter den Linden’ is three streets in one; the Potsdamerstrasse is bordered on both sides by sidewalks which are themselves wider than some of the historic thoroughfares of the old European capitals; there seem to be no lanes or alleys; there are no short-cuts; here and there, where several important streets empty into a common centre, that centre’s circumference is of a magnitude calculated to bring that word spaciousness into your mind again. The park in the middle of the city is so huge that it calls up that expression once more.
