Although Tunisia is smaller than its neighbouring countries, it has a great history, country is very rich with archaeological landmarks. Highlights of Tunisia are:

  • Ruins of Punic, Roman and Byzantine cities. First cities in the present-day Tunisia started to develop almost 3000 years ago and one of them - Ancient Carthage was among the largest metropolises in the ancient world.
  • Medieval cities and towns. Tunisia has some of the best preserved and interesting medieval cities in Arab world, such as the old cities (medinas) of Tunis, Sfax and Sousse.

Cryptozoology is very exciting pseudoscience - a discipline which stands between true science and folklore.

It deals with legendary animals which seem to exist but their existence has not been proved.

Wondermondo provides a unique list of some 50 cryptids which are linked to certain place and observed repeatedly over a longer time period.
