The Romans were on the forefront of many advancements in construction including the creation and implementation of arches and baked bricked. For thousands of years when bricks were created, they were molded and shaped and then left out in the sun to dry and solidify. The Romans came up with the idea to place the bricks in an oven to increase drying time, as well as giving the bricks more strength and durability.
Romans were also the ones to bring the use of arches into architecture. One of the defining characteristics of Roman architecture is the use of arches which also allowed them to build structures in longer stretches.
