EGYPT: Archaeologists Discover 2,600 Year Old Castle On Top Of Another Ancient Structure In Siniai

A former military castle that experts think served as a gate to Egypt's eastern border protecting it from the Persians 2,600 years ago has been unearthed.

Discovered in North Sinai, the fortress is believed to date to 664-610 BC in the Psamtik era - the last before the Persian invasion in 525 BC.

Photos released from the dig reveal a number of items including metal arrow heads, stone daggers and figurines.
