罗马人在建筑方面的最重要的贡献之一是拱门的运用。拱门是一种将重力荷载从上方传递到两侧支撑点的曲面结构。这种技术使罗马人能够建造跨度更大的建筑，并为他们的建筑增添了更大的设计自由度。
混凝土
罗马人还使用了混凝土，这是一种由石灰石、沙子、碎石和水制成的建筑材料。混凝土的使用使得罗马人能够建造更加坚固、耐久的建筑，并能够以更快的速度建造建筑物。
圆顶
罗马人在建筑领域的另一项重要贡献是圆顶的使用。圆顶是一种由多个拱门组成的半球形结构。这种技术使罗马人能够建造更加宽敞、宏伟的建筑，并为他们的建筑增添了更多的美感。
城市规划
罗马人在城市规划方面也做出了重大贡献。罗马人的城市以其井然有序的街道布局、完善的公共设施以及壮观的公共建筑而闻名。罗马人的城市规划为后世的城市规划提供了重要的借鉴。
建筑装饰
罗马人的建筑还以其丰富的装饰而闻名。罗马人经常在他们的建筑中使用雕塑、壁画和马赛克等艺术形式来装饰他们的建筑。这些装饰使得罗马人的建筑更加精美，并反映了罗马人对艺术的热爱。
总之，罗马人在建筑方面做出了巨大的贡献。他们的建筑技术、建筑风格以及城市规划都对后世产生了深远的影响。
