The picture i posted up above is the Eastern gate, this will be the very gate Jesus Christ, the Messiah, will walk through. So it is very significant to us for those who believe in Him.
There is a Muslim cemetery surrounding the sealed entrance. In fact, there is a prophecy  about this very gate, "Then HE brought me back by the way of the outer gate of the sanctuary, which faces the east; and it was shut. The Lord  said to me, "This gate shall be shut; it shall not be opened, and no one shall enter by it, for the Lord God of Israel has entered by it; therefore it shall be shut." Ezekiel 44:1 (New American Standard Bible).
