Temple of Isis
Dedicated to one of ancient Egypt's most important goddesses, the Temple of Isis rises majestically above the calm Nile waters on small Agilkia Island. Some stone blocks found on-site date from 690 BC, but the main part of the complex standing today is from the reign of Ptolemy II Philadelphus (285–246 BC) and the Roman emperor Diocletian (284–305 AD). The devoted worshipped Isis here until the 6th century AD, long after Christianity took hold elsewhere. This building was the final temple constructed in this style, and it's where the last hieroglyph was carved.
The striking, 18-meter (59-foot) First Pylon is one of the temple's oldest structures, built by Nectanebo I (379–361 BC) but showing reliefs from Ptolemy XII (80–58 BC). To reach it, pass the Kiosk of Nectanebo—a roofless structure with offering scenes on its walls and about half of its original Hathor-head columns intact—and go through the First Court, lined with the Roman-built West Colonnade and unfinished East Colonnade.
On the left (west) side of the Second Court is the small mammisi (chapel depicting divine birth), showing the birth of Horus, son of Isis and Osiris. The grand Second Pylon, carved with gods and Ptolemaic-era pharaohs, reveals the entrance to the temple itself. Inside, the Hypostyle Hall consists of 10 columns that are mainly the work of Ptolemy VIII. The generous offering scenes continue, showing the pharaoh by himself or accompanied by his wife giving incense, vases, and wine to the gods. Christians repurposed the temple as a church, as evidenced by the defaced figures and Coptic crosses on the walls. Beyond this area lies the sanctuary, with an altar on the right. A side door leads out to the Gateway of Hadrian, and reliefs show the Roman emperor making offerings to the Egyptian gods.
East of the temple, close to the riverbank, the Kiosk of Trajan is a small open temple with supporting columns. Despite it being unfinished, it's one of Philae's most iconic structures and was often the subject of Victorian-era painters.
Like other ancient structures in Lower Nubia, the Temple of Isis was rescued by UNESCO in the 1970s. After the completion of the Aswan Dam in 1902, water partially submerged the temple during the Nile's flood season, and archaeologists feared that the damp would soften the monument's foundations and cause its collapse. It was moved to what was then known as Agilkia Island but was renamed for the island where the Temple of Isis originally stood.
This temple is one of four ancient monuments in Egypt that has nighttime sound-and-light shows ( soundandlight.show/en, LE310)—the others are Abu Simbel, Karnak in Luxor, and the Pyramids of Giza. Some say that the Philae show is the least cheesy of the bunch. The first part involves walking through the atmospheric, partly illuminated temple, and the second delivers a brief history.
