The flag tower is a symbol of Hanoi
It was built in 1812 under Gia Long Emperor during Emperor Gia Long's reign and is the largest intact construction of the imperial citadel. It is one of the popular tourist attractions, however, it has been marred as visitors carve their names, birthdays or the days they visited the site on the walls. Couples have carved their names and hearts into the brickwork.
There's no comment from the authorities yet on how to restore the tower or deal with the issue.
