唐长安城原是隋朝的大兴城。隋朝成立之初,沿袭西汉的长安城为都。隋朝建立的大兴城在继承古代都城布局制度和吸取历代都城建设经验的基础上现行规划、后施建设、因地制宜、变革求新,开创了中国古代都城营造史上的一个新时代,堪称巅峰之作。唐朝开国时,去除“大兴”之名,后来又以汉唐两座都城本属一地,而恢复使用“长安”旧称。唐长安城位于关中盆地中部,被山带河、沃野千里、物产丰饶,农业发达,四周有泾、渭、浐、灞、滈、沣、 Chang'an City, the original city of Daxing Sui Dynasty. The beginning of the founding of Sui Dynasty, Chang'an City along the Western Han Dynasty are all along. The Daxing City built in the Sui Dynasty inherited the ancient capital city layout system and drawing on the experience of the ancient capital construction on the basis of the current planning and construction, according to local conditions, change and innovation, creating a historic city in ancient China to create a new era, called the peak Make. When the founding of the Tang Dynasty, the name of “Daxing” was removed and later the two capital cities of the Han and Tang dynasties belonged to the same place, and the old saying of “Chang'an” was restored. Chang'an City, located in the middle of the Guanzhong Basin, is surrounded by mountains, rivers and valleys, rich natural resources and developed agriculture. Jing'an, Wei, Xun, Xun, Xun,
