The tallest ancient obelisk in the World is "Lateran Obelisk"

Introduction
Many people probably know the obelisk which stands at the center of plaza or square of famous sightseeing spots such as Place de la Concorde in Paris, Piazza San Pietro in Vatican City, Piazza del Popolo and Piazza Navona in Rome, Hippodrome (Sultan Ahmet Park) in Istanbul, and so on.
Those obelisks were originally erected at the entrance of Ancient Egyptian Temple, and then transported to Ancient Roman Empire which was enchanted by the obelisk, and some of them were made in the Ancient Roman Empire's territories.
Although about 30 ancient obelisks are currently well maintained and stand at the public places (plaza, square, park, etc.), but only 5 remain at the ruins of Ancient Temple in Egypt. And two more obelisks stand at the public space in Egypt. So 7 obelisks in total in Egypt. Therefore, many books and website say: "only few ancient obelisks remain in Egypt".

The obelisks are often referred as a typical examples of antiquities going to foreign countries, because "only few ancient obelisks remain in Egypt" is widely presumed. Also the detailed records, stories and episodes on the obelisks outside Egypt are widely known, but on the obelisks remain in Egypt are few. As the result, "few" and "scarcity" of remained obelisks in Egypt are more emphasized.
When I read such stories, I thought "it's not difficult to see all the obelisks as the numbers are about 30 in 10 countries". Also I felt the enchantment of the visiting tour, because this is not only a pleasure tour, but a World Heritage visiting tour as most obelisks stand in the areas of World Heritage Site.
Then I planned to visit every obelisks in the world. However, I unexpectedly learned many "fragmented" obelisks are not widely introduced yet, and the limited knowledge among the archeologist. Then I finally planned to visit all the obelisks including fragments, and observe by my eyes, and take pictures with high definition image, and report the whole stories including the provenance of the obelisks. This is the motivation for this travel, as my lifework. These websites are as the result of such visiting tours.

Initially I planned to go to Egypt again in Summer 2013 as Egypt is a homeland of ancient obelisks. But I had to abandon the plan as main sightseeing spots are closed due to the sudden military coup d'etat just after purchasing the air tickets. Then I visited Italy instead.
In Summer 2014, I visited Egypt which calmed down the political confusion, and also looked around the obelisks in U.K., Turky and Isreal, and then Italy again.
Then in May 2015, I visited the obelisks which I have not seen in France, Italy, Lebanon, and U.K. As a result, I found that 67 obelisks including the fragmented ones, excluding 26 obelisks remain in the Obelisk Temple in Labanon. And, 60 obelisks (among 67) are publicly exhibited.
