The layer structure of Penrose tiling in the form of Wieringa roof is considered. It is found that each layer can be described by set of overlapped regular pentagonal stars. Local and global pentagonal symmetry of layers can be vividly presented if the stars will be chosen of less size. Linear size ratio of stars in different layers is equal to golden mean or one. It is offered to use four types of star clusters for layer structure description. List of noticed rules of correlation of star location in different layers is proposed. © 2008 IOP Publishing Ltd.
