The most simple are open belfries. Sometimes they have a small roof.

Closed belfries are of different forms. They are square and polygonal, of continuous or complex volume. Their volumes are of homogeneous or different shapes.Belfries with warehouses or out buildings used to be built.

Belfries of a continuous volume are always square in plan.. Sometimes, the upper part of such belfries is open and filled with grating in patterns.

Belfries with two or some equal shape volumes and gradually becoming contracted towards their top have widely spread to Lithuania. They are of square and octagonal plan. Some of such belfries are constructed of hewn lags and others contain the stony lower part, the upper part being of framework. Nevertheless, the majority of them are of stepped framework.

The most simple belfries of such volumes consist of one or two volumes gradually becoming contracted toward the top. In belfries with more different widths in their volumes there are rooflets. The heights of the volumes are often different: the upper or the lower volume is alternately dominant. There are acoustic openings or open galleries in the upper period.

Some part of belfries is constructed of upright-walled and pyramidal volume. The ration between the heights of the volumes is diverse.

Some belfries contain a bell tower and a warehouse or a mortuary. The combination of the two volumes is twofold: a square tower is on a rectangular warehouse roof or near the bell tower, in front or at the side of it there is a low out building.

The architecture of belfries, just as that of other wooden sacred buildings distinguishes itself by its functioning, expressiveness of the proportions and the silhouette and the simplicity of the forms.
