Temple of Edfu. This Ptolemaic temple, built between 237 and 57 BC, is one of the best-preserved ancient monuments in Egypt. Preserved by desert sand, which filled the place after the pagan cult was banned, the temple is dedicated to Horus, the avenging son of Isis and Osiris. With its roof intact, it is also one of the most atmospheric of ancient buildings. You will need to ride the horse carriage to the temple if you come from the cruise. Impressive temple.
