Roman Architecture

I found this website:
www.historyforkids.org/learn/romans/architecture/romarch.htm about
Roman architecture.Romans are famous
for architecture,too.For example,Hadrian’s
Pantheon, a temple to all the gods.Nobody
would build a bigger dome for more than
a thousand years.The Romans brought
a lot of new ideas to architecture, of
which the three most important are the
arch, the baked brick, and the use of
cement and concrete.
We don't have much Etruscan architecture
left.Nevertheless,a lot of their underground
tombs servive.
Page2 talks more about Rome. In the
provinces of the Roman Empire, people were
also building forums, temples, bath buildings,
amphitheaters and apartment blocks.
