It was impressed to be the best day of the whole trip because we are at a height of around 3,700meters and then we went to the Potala Palace. It is an unbelievable historical thing. I cannot find a other word to describe it. It was first built in the 17th century at the time of Sorongchan Gambo, the great king of his time. In the 7th century the fifth Dalai Lama extended the Palace to leads present size. And what a size, it has more than one thousand rooms although, according to our guide, some says it has only 999 rooms. It is located above the village and has a light of 115.7 meters and has 13 stories. Just try to walk up for all the stairs in a nice day with blue sky and temperature around 20 degrees. Remember we are already at 3700 meters. It was a hard walk especially for me and Ola.
