Roman architecture is buildings and structures that were built by the people who lived in ancient Rome. They built lots of things like big buildings called temples, public baths, arenas for games, and houses.
The Romans were really good at building and designing things that were both functional and beautiful. They used materials like stone, marble, and concrete to make their buildings very strong and durable.
One special feature of Roman architecture was their use of arches and domes. They figured out how to build arches and domes that could support a lot of weight without collapsing. This allowed them to build really big buildings like the Colosseum in Rome.
Another special feature was the use of columns. Columns are like big, tall pillars that support the roof of the building. They look really fancy and important. The Romans also liked to decorate their buildings with lots of intricate designs and carvings.
Overall, Roman architecture was very impressive and has had a big influence on the way buildings are designed and built today.
