The dome was a pivotal innovation in Roman architecture because it allowed for the construction of larger, more spacious interior spaces without the need for extensive supports. This design not only enhanced the aesthetic appeal of structures like the Pantheon but also demonstrated advanced engineering techniques, such as the use of concrete. The dome's ability to distribute weight evenly enabled the Romans to create impressive buildings that symbolized their power and ingenuity, influencing architectural styles for centuries to come.
The most important roman legacy for architecture would be the dome. And the most important Roman engineering would be the roads.

Domes were used as roofs for the hot rooms of some bathhouses, which were made in circular shape to accommodate the dome. In the western part of the Roman Empire they were used for a type of temple which had a rotunda with a dome on top. The most famous of these is the Pantheon in the city of Rome, which still has the largest unreinforced concrete dome in the world. In the eastern part of the Roman empire the pendentive dome became popular. It was used to for churches which had two to four domes. It became one of the defining characteristics of Byzantine church architecture

Several ancient Roman buildings had a dome. The most famous one is the Pantheon, which was originally a temple dedicated to all gods. It is well preserved because it was turned into a Christian church. Its dome is still the largest unreinforced concrete dome in the world. However, it is not a central dome. The temple is a rotunda whose wall supports the dome. Other ancient Roman buildings in Rome which had a dome were the Baths of Agrippa, the Baths of Trajan. A Temple in Baiae (near Naples) had a dome. Since the 17th century it has been called Temple of Mercury. Originally it was called Temple of Echo because sounds echoed around the dome. It was the largest dome in the world until the Pantheon was built in Rome. The churches of the Eastern Romans (also called Byzantines) usually had a central dome and sometimes two to four more domes. The most famous of these is the church of the Hagia Sophia in Constantinople (now Istanbul).
