Kinds of classification
Wondermondo has classified the extremely diverse array of landmarks of the world in several ways:

- Categories - classification by the characteristics and origin of landmarks. Currently Wondermondo divides landmarks in three large groups with 28 categories and 38 subcategories.
- Values - classification by the values which make the landmark unique. Below are outlined nine such values.
- Location - classification by the geographical location of landmarks. Described in section Countries.
- Rank - classification by the uniqueness and popularity of landmarks. Described in the section Maps.
Values
Each of the landmarks listed by Wondermondo excels due to certain values. Some are exceptional due to unique art values, others - due to specific importance to science, but some - due to unexplained mysteries linked with them.
In this site there have been identified the following values of landmarks:
Pont du Gard aqueduct, France.

Wondermondo hates classification and categorization. World is too beautiful and too diverse and it is interesting just because it can not be fully comprehended. Who has heard about the classification of wonders?
Morning Glory, Queensland. Definitely a wonder - but in which category it belongs?

But the enormous number of wonders without any classification would lead to chaotic congregation of information. And there is little sense for information if it can not be found. Thus Wondermondo offers own system of classification.
Categories
Categorisation of the wonders of the world is complex issue as there many ways making these wonders amazing and unique.
The list below is made throughout several years of work - sometimes extending it to more than 100 categories and sometimes even approaching an illusory feel of order. It is not complete so far and will be updated upon necessity.
The list of categories bears no unified principles and many landmarks of the world fit into several categories. One principle though has remained strict - every valuable monument of the world would fit at least into one of these categories.
Many categories have also subcategories - here are listed those which are met most frequently.
