The Nabataeans' reign over Petra ultimately met its end in 106 AD when the Roman Empire annexed the kingdom, marking the beginning of the city's decline. The Romans maintained a presence in Petra for several centuries, but their rule was marked by political instability and economic decline. The city's once-thriving trade routes dwindled, and Petra gradually fell into ruin. Despite the decline, Petra's architectural wonders and intricate water management systems continued to captivate visitors, ensuring its legacy as a testament to the ingenuity and artistry of the Nabataeans.
