Trajan's Kiosk is a hypaethral temple located on Agilkia Island  One of the largest Ancient Egyptian monuments standing today  it was constructed by the Roman Emperor  Trajan. The edifice was originally built on the island of Philae  near the lower Aswan Dam  However, it was later transported to Agilika in the 1960s by UNESCO to save it from being enveloped by the rising waters of the Nile due to the construction of the Aswan High Dam 

This 15-x-20 metre kiosk is 15.85 metres high  its function was likely to shelter the bark of Isis at the eastern banks  of Philae island Its four by five columns each carry different  lavishly structured composite capitals that are topped by 2.10-metre-high piers  and were originally intended to be sculpted into Bes piers  similar to the birthhouses of Philae  Armant  and Dendera though this decoration was never completed  

The structure is today roofless but sockets within the structure's architraves suggest that its roof  which was made of timber  was indeed constructed in ancient times . Three 12.50-metre-long  presumably triangulated trusses  which were inserted into a ledge at the back of stone architecture  carried the slightly vaulted roof.  This building represents an example of the unusual combination of wood and stone in the same architectural structure for an Egyptian temple
