The Red Castle Museum, also known as As-saraya Al-hamra Museum (Arabic: متحف السرايا الحمراء), the Archaeological Museum of Tripoli or Jamahiriya Museum, is a national museum in Libya. It is located in the historic building known as the Red Castle of Tripoli (Arabic: السراي الحمراء), sometimes also referred to as Red Saraya, on the promontory above and adjacent to the old-town district with medina Ghadema. Designed in conjunction with UNESCO, the museum covers 5,000 years from prehistory to the independence revolution (1953) era. The museum has an entrance on historic As-Saha al-Kradrah, the Martyrs' Square. The museum has been closed since 2011 due to security concerns.
