Seoul gears up to welcome 1 mil. pilgrims for 2027 World Youth Day

World Youth Day 2027 will bring hundreds of thousands of international and domestic pilgrims to Seoul from Aug. 3 to 8, 2027, with up to 1 million expected at the closing Mass in Seongnam, Gyeonggi Province. Archbishop Peter Chung Soon-taick said the gathering aims to encourage connection and welcome amid young people’s isolation and social division. The program includes an opening Mass, a welcome for Pope Leo XIV, an overnight vigil and a closing Mass. Organizers are preparing crowd-safety measures and a five-day program in regional dioceses.

The organizing committee expects 400,000 international pilgrims from around 190 countries and 100,000 domestic participants.

More than 81,000 participants had completed registration as of Nov. 5.

The event is the 17th international World Youth Day and the second held in Asia, following Manila in 1995.

Organizers selected Seoul Air Base for the overnight vigil and closing Mass to minimize traffic disruption and support crowd safety.

The committee plans to use AI-based density monitoring, crowd-movement simulations, emergency medical teams, shade, drinking water and cooling equipment.

Archbishop Chung calls for human connection in digital age

Up to 1 million people are expected to gather in Seoul for the closing mass of the 2027 World Youth Day (WYD), marking a historic moment as the global Catholic youth festival is held for the first time in a country where Christians do not hold a majority in the population.

The WYD Seoul 2027 event, running from Aug. 3 to 8, 2027, will bring an estimated 400,000 international pilgrims from around 190 countries together with 100,000 domestic participants, the organizing committee said, Thursday.

Sharing its detailed roadmap for the international event, Archbishop Peter Chung Soon-taick of the Archdiocese of Seoul emphasized the deeper meaning of the gathering, pointing to the isolation faced by younger generations in the digital age.

"We live in an era of disconnection," Chung, who also serves as head of the organizing committee, said at Myeongdong Cathedral in central Seoul.

"While we can reach each other instantly through the screens in our hands, it has become much harder to truly know one another. Young people today face constant comparison and competition, and even how we judge a person's value is changing quickly because of technologies like AI (artificial intelligence)."

The archbishop stressed that a person's worth is not defined by wealth or social position. He urged people to show courage in bringing together a divided society.

"What we want to achieve in Seoul in the summer of 2027 is not just gathering a large number of people in one place," Chung said. "What we need in this age of disconnection is the courage to meet and the courage to welcome others."

The 2027 gathering in Seoul marks the 17th international edition of WYD since its inception in Rome in 1986. It is the second time the global event will be hosted in Asia, following the 1995 event in Manila, the Philippines, and the first time it will take place in a country where Christianity is not the majority religion.

The event will begin with an opening mass on Aug. 3, followed by a welcoming ceremony for Pope Leo XIV at Seoul World Cup Stadium in western Seoul. An overnight vigil and closing mass will take place at Seoul Air Base in Seongnam, Gyeonggi Province, which is expected to accommodate a crowd of up to 1 million participants.

Preparing venues with safety in mind

Bishop Paul Lee Kyung-sang, coordinator for the organizing committee, said the committee selected Seoul Air Base to minimize traffic disruptions and ensure safety for the anticipated crowds.

He added that the dates were chosen by checking weather statistics to avoid heavy monsoon rains and peak typhoon season while ensuring university facilities remain available for lodging.

"Over 81,000 participants have already completed their registration as of Nov. 5," Lee noted. "We are working with local parishes and governments to secure enough lodging, and everything is progressing smoothly so far."

Safety remains the top priority for organizers, who are preparing comprehensive measures against summer heat waves and crowd congestion. The committee plans to deploy AI-based density monitoring systems and emergency medical teams in cooperation with the government and local authorities.

"We will apply advanced crowd movement simulation programs and use closed-circuit televisions with artificial intelligence to analyze on-site crowd density," Lee said. "We will work closely with firefighters and police to ensure a swift response, and we are preparing shade, drinking water and cooling equipment to protect participants from extreme heat."

Prior to the main gatherings in Seoul, a five-day diocesan program will take place across 15 regional dioceses starting July 29, allowing international youth to experience local culture and traditions before heading to the capital.

预计将有多达 100 万人聚集在首尔参加 2027 年世界青年日 (WYD) 的闭幕弥撒，这将具有历史意义，因为这一全球天主教青年节首次在一个基督徒人口不占多数的国家举行。

世界青年日首尔2027活动将于2027年8月3日至8日举行，届时将有来自约190个国家的约40万国际朝圣者和10万国内参与者齐聚一堂，组委会周四表示。

首尔总教区总主教郑顺泽分享了此次国际活动的详细路线图，并强调了此次聚会的深层意义，指出年轻一代在数字时代面临的孤立感。

“我们生活在一个人与人之间疏离的时代，”郑元畅在首尔市中心的明洞大教堂说道。他同时也是本次活动的组委会主席。

“虽然我们可以通过手中的屏幕瞬间联系彼此，但真正了解彼此却变得越来越难。如今的年轻人面临着持续不断的比较和竞争，甚至我们评判一个人价值的方式也因为人工智能等技术而迅速改变。”

大主教强调，人的价值并非由财富或社会地位决定。他敦促人们展现勇气，弥合社会的分裂。

“我们希望在2027年夏天在首尔实现的，不仅仅是将大量人群聚集在一起，”郑先生说。“在这个人与人之间疏离的时代，我们需要的是相聚的勇气和接纳他人的勇气。”

2027 年在首尔举行的世界青年日是自 1986 年在罗马创办以来的第 17 届国际盛会。这是继 1995 年在菲律宾马尼拉举办之后，该全球盛会第二次在亚洲举办，也是首次在基督教并非主要宗教的国家举办。

此次活动将于8月3日以开幕弥撒拉开帷幕，随后在首尔西部的首尔世界杯体育场举行欢迎教宗良十四世的仪式。通宵守夜和闭幕弥撒将在京畿道城南市的首尔空军基地举行，预计将有多达100万人参加。

以安全为首要考虑准备场地。

组委会协调员保罗·李京相主教表示，组委会选择首尔空军基地是为了最大限度地减少交通中断，并确保预计人群的安全。

他还补充说，选择这些日期是查看了天气统计数据，以避开季风强降雨和台风高峰期，同时确保大学设施仍然可供住宿。

李指出：“截至11月5日，已有超过81000名参与者完成了注册。我们正在与当地教区和政府合作，确保有足够的住宿，目前一切进展顺利。”

安全仍然是组织者的首要任务，他们正在制定应对夏季热浪和人群拥堵的全面措施。组委会计划与政府和地方当局合作，部署基于人工智能的密度监测系统和应急医疗队。

李说：“我们将运用先进的人群移动模拟程序，并利用闭路电视和人工智能技术分析现场人群密度。我们将与消防员和警察密切合作，确保快速响应，同时我们也在准备遮阳设施、饮用水和降温设备，以保护参与者免受酷暑侵袭。”

在首尔举行主要集会之前，从 7 月 29 日开始，将在 15 个地区教区举行为期五天的教区活动，让国际青年在前往首都之前体验当地的文化和传统。
