On 29 November 2009, parts of
Sejong-ro were closed to traffic for twelve hours to film lengthy gunfight scenes for
Korean Broadcasting System (KBS)'s 2009 spy action television drama series "
Iris," starring
Lee Byung-hun,
Kim Tae-hee,
Jung Joon-ho,
Kim Seung-woo and
Kim So-yeon. The five lanes along the square in front of the
Sejong Center for the Performing Arts were closed to traffic from 07:00 to 19:00, while the five lanes on the
Kyobo Book Centre side remains open to traffic. This marks the first time the
Seoul Metropolitan Government has granted permission to block traffic along the square for filming and it is part of the government's plans to promote the city's major tourist attractions, including
Cheonggye Stream and
Han River. On 26 July 2012 at 23:00, boy band
Beast held a
guerrilla concert at the Gwanghwamun end of the square in front of an audience of 4,000 people. It was part of their promotion for their fifth mini album "
Midnight Sun," and the performance was broadcast on
SBS's music show "
Inkigayo." In 2012, the square was used as a filming location for
tvN drama "
Queen and I." The two lead characters Kim Boong-do and Choi Hee-jin (played by
Ji Hyun-woo and
Yoo In-na, respectively) share a kiss dubbed the "Gwanghwamun kiss" against the backdrop of Gwanghwamun.
Kyuhyun, of boy band
Super Junior, used the location as a theme for his 2014 chart-topping single, "
At Gwanghwamun." His label-mate
Jo Sung-mo, of
TRAX, recorded a live electric guitar cover of the song with Gwanghwamun Gate in the background. In February 2026, it was announced that boy band
BTS would hold a concert titled "BTS The Comeback Live |
Arirang" on 21 March 2026, and that the performance would be broadcast live globally on
Netflix. It was the band's first concert together since 2022 following a hiatus to fulfill their
mandatory military duties. The event drew over 100,000 attendees, fewer than the 260,000 people anticipated, while an estimated 18.4 million people worldwide watched the broadcast on Netflix. It was hosted and organized by
Big Hit Music and
Hybe. ==Transport==
