Another example of Roman architecture is the Colosseum. It was built between 72-107 ad. Vespasian worked on the structure. When he died, Titus worked on it. Domitian finished it after Titus died a year later. (See paragraph 4 for details in more architects) It has gigantic arches. They are even taller in person than they look online! One arch alone is the size of 5-6 average human adults. These arches were held up because the Romans used a strong concrete to build their work. The Romans had perfected the use of a concrete that the Greeks used to use the build things. They mixed volcanic rock and limestone to create a mortar, which is a type of paste-like glue that can join blocks of concrete together.This section is about examples of amazing Roman architects that created very important structures in the ancient world. A very amazing architect named Marcus Vitruvius Pollio was hired to be an architect of Julius Caesar in between 58 and 51 BCE. He traveled to many places around the Mediterranean area and studied architecture. He created a text named, “De Architectura”, which translates to “By Architecture” directly in English. Vitruvius was one of the best Roman architects out there at the time, and there were very little people who even came close to his accomplishments. It was not until half a century later that Apollodorus was recognized. He was from Damascus, currently located in Syria (but this was Roman territory at the time). He created many structures, but his 2 most popular accomplishments were Trajan’s Column and Trajan’s Forum. The column was almost 100 feet tall and celebrated the victory of the Tarjan army over the Dacian army. Trajan’s Forum was a public square that surrounded Trajan’s Column, which was 980 feet long and more than 600 feet wide! The smart Roman architects have created many beautiful creations, especially when adding their materials, columns, and arches to the mix. If these creations didn’t exist, we wouldn’t be presented with not only the beauty of the products the Romans created but also the intelligence of the workers.
