Ancient buildings from Roman times seem to be built for eternity and are obviously a very special building material.
The Pantheon is one of the most famous buildings of ancient Rome, still defying the elements after almost 2000 years. Numerous amphitheatres such as the Colosseum, huge aqueducts and harbour facilities are just as old today. In Spain, Greece and Turkey, the sturdy, millennia-old buildings of the Romans can also be found. Modern concrete buildings, on the other hand, only have a lifespan of 100 years, while our motorways and bridges have only lasted 50 years.
