Qasr al-Farid is situated all by itself in a separate rocky outcrop and includes an architectural feature not found in other tombs, namely the two Nabatean columns found on the lower part of the facade, as well as the side columns.
The tomb was never completed, as is especially evident in its lower portion and the open space before the entrance.
The foundation inscription of the tomb, which reads "For Hayyan bin Kuza and his descendants," is undated.
