尼莎帕提亚要塞由新旧两组台形遗址构成，展示了帕提亚王国最早和最重要的城市遗址。帕提亚王国是公元前3世纪中期至公元3世纪的大国。在近两千年的历史中，这里几乎从未遭到破坏，将古代文明的发掘遗址保存下来，并巧妙地将自身的传统文化元素和希腊及西罗马元素结合起来。对两处遗址进行的考古挖掘发现了装饰精美的建筑，展示了室内、城邦和宗教方面的功能。挖掘工作一直在皇家城堡内进行，现在被称为“老尼莎”。这处遗址还包括被称为“新尼莎”的古代城镇。老尼莎是占地14公顷的台形土墩，形状为不规则的五边形，四周是建有40多个矩形塔台的防御土墙，与各个墙角侧面相接的是坚固的棱堡。占地25公顷的新尼莎四周是高达9米的围墙，有两个入口。坐落在重要的商业和战略枢纽交叉路口的尼莎考古遗址，生动地展现了中亚和地中海地区对大国文化影响之间的互动，在充当东西方、南北方之间重要的通讯和贸易中心的同时阻挡了罗马的扩张。这一遗址见证了帝国的重要性、财富和文化。

Nisa was the capital of the Parthian Empire, which dominated this region of central Asia from the mid 3rd century BCE to the early 3rd century CE. As such it formed a barrier to Roman expansion, whilst at the same time serving as an important communications and trading centre, at the crossroads of north-south and east-west routes. Its political and economic power is well illustrated by the surviving remains, which underline the interaction between central Asian and Mediterranean cultures. Criterion (ii): Nisa is situated at the crossroads of important commercial and strategic axes. The archaeological remains vividly illustrate the significant interaction of cultural influences from central Asia and from the Mediterranean world. Criterion (iii): The Parthian Empire was one of the most powerful and influential civilizations of the ancient world, and a brilliant rival of Rome which prevented the expansion of the Roman Empire to the east. Nisa, the capital of the Parthian Empire, is the outstanding symbol of the significance of this imperial power. The integrity and authenticity of the property, and also of the surrounding landscape, in terms of the size of the two tells and the siting of the capital at the foot of the Kopet-Dag mountains, are unquestionable. The two tells do not in any sense represent the original appearance of the Parthian capital, but their present appearance is due solely to natural erosion. The site is gazetted as one of the 1,300 historical and cultural monuments of Turkmenistan. Nisa is also one of the eight State Historical and Cultural Parks (SHCP) that have been created to protect the most significant sites in Turkmenistan. A buffer zone has been established. The property comes within the provisions of the Bagyr town development plan. Serious efforts are still needed to set up an efficient preventive maintenance scheme that will ensure the survival of recently excavated parts of the site. A five-year plan has been formulated for 2006-2010, in order to ensure a better balance between the different activities (e.g. archaeology vis-à-vis conservation) and to combine and harmonize all the existing documents and strategies relating to the site.
