With most independence and most emphatically, however, it is the _towers_ which rise upwards in their sublime summits. In other words we find that the entire mass of the building concentrates among other things itself in them, in order that thus in its main towers it may be without hindrance uplifted to an incalculable height without thereby losing its character of repose and stability. Such towers are either placed in the principal façade over the two side entrances, while a third and broader main tower springs up at the point where the vaulting of the transepts, choir, and nave meet, or one single tower constitutes the principal façade and is raised above the entire breadth of the nave. Such are at any rate the positions which are most usual. In direct connection with the worship such towers have belfries, that is, to the extent that the ringing of bells properly applies to Christian services. This merely indefinite tone of the bell is a solemn stimulus of the soul-life, though in the first instance one that as yet prepares the worshipper only on the outside of the building. The articulate tone, on the other hand, wherein a definite content of feelings and ideas is expressed, is the song which is only to be heard within the church. The inarticulate clang of the bell finds its right place on the outside and only there and is sounded forth from the towers that its peal may pass forth as from some pure height far over the land. (_c_) As to the mode of decoration I have already pointed to the main features of determinate character.
