Etrustcans invented Gladiator fights. They also invented some things in artchecture.

Stone and clay was used and packed to form the arch of Augustus. Their were two.
Apart from the fact that the it is thought that Etruscans invented the simple barrel arch and that the Roman adopted it, not much is known about the Etruscan influence on Roman engineering due to a lack of archaeological finds. The Etruscan had an influence in the archaic (early) period and then their civilisation decayed. Very little of their writing has survived and their language has not been fully deciphered. The Romans did not write much about Etruscan influence.
The Arch of Constantine was made of brick and marble. There is a link below to an article on it.
the marble arch was made in 1867
It is not really known because Etruscan influence occurred very early in Roman history and there are very little archaeological remains from that period. Very little has survived due to both the early age and because ancient Rome was continuously being redeveloped in her 1,200 years of history. It is thought that the Etrucans developed the barrel arch, the simplest type of arch. The Romans then developed the vaulted arch which is more complex. It is likely that some of the archaic (early) Roman temples might have been built in the Tuscan (Etruscan) architectural order. However, if so, they did not survive and this order was soon abandoned in favour of the Greek architectural orders because it was seen as too simple and rustic. The theory that the Etruscans conquered Rome in the 6th century BC, were responsible for Rome's earliest urbanisation and built the Cloaca Maxima (a sewer) and the large temple of Jupiter Otpimus Maximus on the Capitoline hill is just that, a theory. Its evidence base if flimsy and it is based on unproven assumptions. It has been challenged. Recent archaeological evidence in Latium (land of the Latins) suggests a different picture.
The "skin" of the arch is stainless steel.
