The Kotel (Western or Wailing Wall) is considered to be the holiest easily accessible place. The Kotel is a remnant of the walls that surrounded the Temple Mount. In practice the Southern Wall (Davidson Center) is also holy also being a wall of the Temple compound. When visiting the Kotel Tunnels you can get to the point physically closest to the site of the Holy of Holies - a small prayer alcove marks the spot and is considered by many to be the holiest of sites easily available to Jews today. The real holiest site is the Temple Mount itself - where the Temple stood before its destruction by the Romans in year 70. However, access to the site is severely restricted today - due to a combination of ritual purity issues and political restrictions due to the fact that the Temple Mount is currently occupied by the Dome of the Rock ( a holy site to Muslims) The Temple mount and its adjacent Western ("Wailing") Wall.
There are quite a number of such sites, but the most famous is the Temple-Mount/Noble-Sanctuary area in the Old City of Jerusalem. It is the holiest site in the world to Jews and the third holiest site in the world to Muslims.
