One of, if not the most important centres for justice and peace in the world, Peace Palace comprises the United Nations International Court of Justice, the Permanent Court of Arbitration, the Hague Academy of International Law and the Peace Palace Library. Although this is a working palace, which means most areas are closed to the public, there is, however, a visitors centre where those interested can learn more about the history of the palace and the role it plays today in international justice via a free audio tour. On rare occasions, the palace opens its doors to the public for guided tours, but it is advisable to check well in advance if any dates are available as they are few and far between. In any case, the impressive surrounding gardens and Neo-Renaissance buildings are definitely a must-see.

During Roman times the Cardo was Jerusalem's main street, and it must have been quite a view: lined by columns that linked as roofed arcades above pedestrians, it was 22 meters wide and teemed with carriages and cattle. The street has been rediscovered and partially restored by archaeologists in 1975. While walking, you'll see the wall remains of the First and Second Temple, columns, and typical stone brick pavements. In the north, there is an authentic bazaar which dates back to the Crusades era.
