UNESCO "seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of
outstanding value to humanity."
quoted from the Unesco website
There are 788 sites that have been elected world heritage sites covering pretty well every country of the world. This is embodied in an
international treaty called the Convention concerning the Protection of the World Cultural and Natural Heritage , adopted by UNESCO in 1972.
Cultural heritage refers to monuments, groups of buildings and properties with historical, aesthetic, archaeological, scientific, ethnological
or anthropological value. Natural heritage refers to outstanding physical, biological and geological formations, habitats of threatened species of animals and plants and
areas with scientific, conservation or aesthetic value.
Medina of Essaouira (formerly Mogador) (2001)
Originally intended to go there but as we are short on time - have to
be in Casa for the Tour de Maroc on the 26th March we've run out of
time. Everyone says it's a fabulous place - so maybe we wouldn't like it
- we often find we don't when too may tourists recommend somewhere! but
to be fair many Moroccans have recommended it too.
Portuguese City of Mazagan (El Jadida) (2004)
Again - ran out of time - but we don't feel terribly upset -= first El
Jadida was only declared a World Heritage site late last year - so it's
taken them some time to decide it is special! Also we went to Sete -
which is a twin city to El Jadida - yes ok - it's definitely a cheat but
we have to be cheeky sometimes!
