Rating of wonders

WorldBlue Four criteria

Kaaba, golden door visible, Saudi Arabia
Kaaba in Makkah (Saudi Arabia) has the highest rating on Earth in the criteria “Story” – 96%. The total weighted rating though is 74.7 (22nd place) because this wonder leaves a lower visual impression if compared to many other wonders around the world. / Tab59, / CC BY-SA 2.0

The rating of wonders in the Wondermondo site has a gradation from 0 (least wondrous) to 100 (most wondrous). This rating is calculated with a special formula, using the data of four criteria. These criteria are:

  1. Visual impression. This is the impression that is created by the wonder on human eyes and other senses. High visual impressions can be created by very ornate buildings, the extreme size of the object, or very unusual sight.
  2. Story. Wonders often are defined by unusual facts or events. These can be important scientific discoveries – e.g. a cave with remnants of another human species but this can be also an unusual story or tradition, e.g. islands where according to local legends live the spirits of deceased people.
  3. Uniqueness. This criterion is assessing the rarity of the wonder in the world. Very few wonders are truly unique.
  4. Mystique. A minor part of wonders (some 3%) has some unexplained features. Most likely, an explanation exists but it has not been found yet. Most frequently these are sites of ghost stories and stories about legendary animals (cryptozoological phenomena) but there happen to be also some very unusual natural phenomena.

Further below are listed the 10 very best wonders after a thorough analysis of more than 11 500 wonders of Earth!

What is a wonder?

Many wonders are linked to a certain place. The aim of Wondermondo is to list and describe such places all around our planet. Thus, the name “wonder” on this website means a surprising place on our planet.
