We took the subway three stops to Freedom Square, where the subway and the Baku Metro are the same ticket system, each one-way 0.5 GEL, equivalent to RMB 1.3 yuan. It's cheap enough. Freedom Square belongs to the downtown area of Tbilisi. The square was built in the 19th century under the rule of Russia. Originally it was called Eriwen Square. In the Soviet era, it was renamed Lenin Square. After Georgia's independence in 1991, it was renamed Liberty Square. The statue of Lenin in the square has now been replaced by St. George's dragon slaughter column. The tall column under the blue sky and white clouds seems to announce the changes of history in this country. The buildings around Freedom Square were mostly built in the Russian and Soviet times, including the Tbilisi City Hall, the Georgian National Gallery of Art, Marriott Hotel and so on. Near the square is the old Georgian city that existed before the 19th century. In the evening, we said goodbye to the fortress, walked through the old city of Tbilisi in the dark, hiked for more than half an hour, and then returned to the bright Liberty Square. The scenery we saw now was quite different from that under the blue sky and white clouds in the afternoon.
