Eight different fortifications of unequal size and strategic importance are tackled in this contribution, namely the ones along the Danube limes, starting at Seimenii Mari, Stânca Topalu - Cariera Cekirgea, Cius - Gârliciu, Luncavița - Milan, Isaccea - Noviodunum, Tulcea – Aegyssus, and two more Late Roman quadriburgia, controlling the inner roads at Mihai Bravu and Mircea Vodă. Excepting for Noviodunum and Aegyssus, none of the above mentioned limes forts was subject to thorough archaeological investigations which is why all of them entered lately into the scope of the Romanian LIMES National Programme. As a matter of fact, within the framework of the World Heritage List nomination preparings, the entire Lower Danube Roman frontier became subject to detailed surveys and drone flight records (with orthographic and oblique shots) which were corroborated with all the information available so far in the archives. Therefore, a partial Forschungsstand for all this intensive research is presented in the following pages. Our approach is formally a holistic one, aiming at integrating and understanding the dynamics of both limes and interior communities, covering their communication mediums, landscape and resources. In this respect, new promising steps were also taken for identifying civitas Ausdecensium at Cetatea (commune of Dobromir, Constanța county), in southern Dobrudja. What we already know for sure is that in the 4th century the members of a prosperous habitation along the imperial road from Marcianopolis, running through Zaldapa, Tropaeum Traiani (possibly, Mircea Vodă) and Ulmetum, to Noviodunum peacefully dwelt within the area of the modern village.

多布鲁贾的罗马边境。若干未挖掘或平面特征未确定的防御工事

这份贡献中涉及了大小和战略重要性不同的八个不同的防御工事，即多瑙河沿岸的防御工事，从 Seimenii Mari、Stânca Topalu - Cariera Cekirgea、Cius - Gârliciu、Luncavița - Milan、Isaccea - Noviodunum、Tulcea - Aegyssus、以及另外两个罗马晚期的 quadriburgia，控制着 Mihai Bravu 和 Mircea Vodă 的内部道路。除了 Noviodunum 和 Aegyssus，上述石灰堡垒都没有经过彻底的考古调查，这就是为什么它们最近都进入了罗马尼亚 LIMES 国家计划的范围。事实上，在世界遗产名录提名准备的框架内，整个下多瑙河罗马边境都受到了详细调查和无人机飞行记录（包括正射和斜射）的影响，这些都得到了档案中迄今为止可用的所有信息的证实。因此，所有这些深入研究的部分 Forschungsstand 将在以下页面中呈现。我们的方法在形式上是一种整体的方法，旨在整合和理解石灰和内部社区的动态，涵盖它们的传播媒介、景观和资源。在这方面，在 Dobrudja 南部的 Cetatea（康斯坦察县 Dobromir 公社）也采取了新的有希望的步骤来识别 civitas Ausdecensium。我们已经确定的是，在公元 4 世纪，沿着从马尔恰诺波利斯出发，穿过 Zaldapa 的皇道沿线的繁荣住宅的成员，
