Hundreds of skilled stonemasons were used in the construction

The timescale was tight - the Flavian family wanted the amphitheatre built as quickly as possible. Hundreds of skilled stonemasons were required to complete the building. The Romans used a new building technique - standardized parts. Stairs and seats were constructed off-site. The stairs and seats were all built to the same size and were made to be interchangeable. They were made in workshops and then brought to the amphitheatre to be fitted by teams experienced in this work.
