Oh I think you are talking about the Zabeel Palace, that has the horses carved at the top of the entrance.
But I mean in Nad Al Sheba (1), somewhere along the same road as where the NAS gym is located, there is a roundabout fully decorated with horse carvings and to the right of this roundabout is the restricted entrance.
Ah! Then no that’s not where shiekh Hamden lives , that is a private entrance to another palace
