Seoul is transforming itself into an extended concert venue ahead of BTS' comeback show Saturday, with the city government rolling out a month of landmark light displays, themed festivals and guided tours designed to give the hundreds of thousands of fans — collectively known as ARMY — more than a single night out, the Seoul Metropolitan Government announced Monday.

Starting Friday, the day the highly anticipated album "Arirang" drops, 15 city landmarks, including Sebitseom and Cheonggye Stream, will be lit in red — the color associated with the new album — to mark their return, turning the skyline into a dynamic nighttime stage. City officials say the lighting is designed to make Seoul feel like a giant open-air performance space.

To demonstrate the city’s welcome, greeting banners will be hung along Sejong-daero near the Gwanghwamun concert venue and welcome messages will be displayed on 10 media facades across the city. Major tourist spots and traditional marketplaces will also show welcome phrases in English, Chinese, Japanese, Vietnamese, Indonesian, Thai and Korean.

On Saturday and Sunday, the Banpo Bridge Moonlight Rainbow Fountain in southern Seoul will stage a BTS-themed nighttime show set to the group’s music, combining LED lighting and a kilometer-long display along the Han River.

Cheonggye Stream will be decorated as a BTS walking zone from April 6 to 19, when a 500-meter stretch between Ogan Bridge and Beodeul Bridge is transformed into an “Arirang Light Walk” using BTS-themed symbols.

As many as 260,000 people are expected to gather in central Seoul for the concert, pushing authorities to roll out some of the toughest crowd-control measures the city has ever used for an outdoor event.

Police will deploy about 6,500 officers from riot, traffic, crime and special forces units, along with 5,400 pieces of equipment, including high-altitude surveillance vehicles, to manage the flow of people around Gwanghwamun Square.

As part of those measures, the area will be divided into controlled zones and all spectators will be funneled through 31 designated gates before they can enter viewing sections. Access to 31 nearby buildings will also be restricted: Six buildings that directly face the venue are being asked to close their main entrances and keep only back doors open, while another 25 have been urged to block entry to rooftops and upper floors to prevent unsafe viewing.

Public transport around the venue will be adjusted on the day of the show. Trains will skip City Hall Station on Lines 1 and 2, Gyeongbokgung Station on Line 3 and Gwanghwamun Station on Line 5 during peak concert hours, and some bus routes and public bike docks in the area will be suspended or rerouted to keep streets clear for emergency cars and ease pressure on key access points, according to city officials.

Beyond the BTS concert weekend, the city government plans to tie the event to a broader spring tourism push centered on the 2026 Seoul Spring Festival along the Han River from April 10 to May 5 —for visitors who remain in Seoul after the concert.

The festival will feature laser and fireworks media shows, hands-on experiences along the river and a drone light show on opening night in Yeouido. Seven Hangang Bus docks will be opened as rooftop viewing spots and a one-day unlimited Hangang Bus pass will be available on March 20 and 21 so visitors can move between key locations including Sebitseom and N Seoul Tower, city officials said.

Dongdaemun Design Plaza will host a music light show from April 6 to 12, offering a separate cluster of nighttime content for visitors. Meanwhile, rooftop antenna shops will run K-culture experience programs, while the newly opened Seoul Gallery will operate as a special welcome venue during the event period.

The Seoul city government is also developing guided walking tours that trace BTS-related landmarks, including music video filming sites and entertainment agency buildings, available via the VisitSeoul website, official city social media channels and fan communities.

“We have prepared a variety of attractions and experiences so that, beyond the concert itself, the city of Seoul can serve as cultural content in its own right,” said Kim Myung-joo, director general at the city government’s sports and tourism division.

“We’ll put safety first and prepare thoroughly, while actively helping global fans experience Seoul’s many facets through a wide range of cultural and tourism content linked to the concert.”
