In the 16th CE, after the Turks captured Jerusalem, the room was transformed into a mosque in memory of the prophet David. This is the mihrab.

Is this the Tree of Life? No idea why it was put here

Like all sacred places, this, too is guarded by its own guardian...

This is the upper room where the Last Supper was held. It is only opened twice a year

Next, I passed by the Chamber of the Holocaust... didn't have time to visit but someone said it is more powerful than Yad Vashem...

Finally found the King David's Tomb. Actually we knew it is right below the Hall of the Last Supper, but just could not find the entrance. Anyway it was closed by the time I found it

The Christian cemetery containing the grave of Oskar Schrinder. Yes, the same Schrinder in Schrinder's List.

Last is the Church of St. Peter in Gallicantu

This was the site where St. Peter denied Jesus 3 times. (Mark 14:66-72) 'Before the cock crow thou shalt deny me thrice'

As it was closed so I could only take a shot through the gates before the security threatened to call the police to take me away

Zion Gate. This connects the old city and Mt. Zion

To pass the gate you actually need to take a doglegged tunnel (which was not so safe given the number of cars driving through) The design was to slow down advancing enemy forces)
