Marid Castle (or Marid balance) is a historic military fortress located in the city of Dumat Al-Jandal in the Al-Jawf region, about 50 km away from Sakaka . It dates back to the first century AD, and the oldest mention of it dates back to the third century AD when the Queen Zenobia (240 - 274) invaded Dumat al-Jandal and Tayma, and she could not storm the fortress. Therefore, she said: “ Marid has rebelled, and Ablaq has glorified.”
