The Colosseum and Tuff
Rome gets the world's biggest Colosseum, a Roman amphitheatre with the best capacity in the entire world. The amphitheatre was built of travertine limestone, and it had been the largest amphitheater ever assembled then. In its stunning grandeur, the Colosseum will transfer you back into the ancient Roman age.
The Colosseum is not just a huge spectacle, but it's also a rather important architectural masterpiece of historical Rome. Its original structure is believed to have been completed by the Romans themselves, with the majority of the stones used being quarried nearby. The stones were transported to Rome and they had been put in such a manner it was allowed for them to be easily aligned by the use of hydraulic jacks. The Colosseum is made from travertine and brick-faced concrete.
Construction of the Colosseum was performed in 31 B.C. and it was a massive job for the people involved. The largest and most complex construction project of that time, it had been the greatest amphitheater ever built in Roman history. As it stands today, it had been expanded and redecorated in a number of distinct ways.
The structure of the Colosseum is composed of marble columns and travertine and brick-faced concrete. These are put in a grid pattern to make a huge space that can hold up to eight million people at a time. A few of the columns are even as tall as the terrace of the Colosseum itself, a few around seven and a half metres . These columns support the massive floor of the Colosseum, the 2nd biggest stone surface on the planet.
The large floor of the Colosseum consists of travertine limestone. This is a naturally occurring limestone found on the mountain of Mount Vesuvius. It consists of different colours depending on what part of the planet it is mined from, which range from purple to orange. Travertine is an extremely tough material, making it ideal for use in massive buildings such as the Colosseum, because it is not subject to wear and tear and cracking as is frequently the case with other kinds of rock.
There is a special technique used in constructing the Colosseum, where travertine and concrete are mixed together. This is referred to as tufo, which means"sand and cement." This is done in a large kiln, and then the mixture is heated and pushed into shape. From the Colosseum, this tufo mixture is laid inside the building, under pressure, which results in the mixture to bond together.
