Trajan's Kiosk
ZT from http://en.wikipedia.org/wiki/Trajan%27s_Kiosk

Trajan's Kiosk, a hypaethral temple, is one of the largest Ancient Egyptian monuments standing today at the island of Agilkia, which was constructed by the
Roman Emperor, Trajan. It was originally built at the island of Philae (near the lower Aswan Dam) but 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.
