Gyeongbokgung Palace.

Built in 1395, Gyeongbokgung is the primary and largest of Seoul’s Five Grand Palaces, serving as the seat of power for the Joseon Dynasty for centuries. Though much of the original complex was destroyed over time, ongoing restoration projects have meticulously revived its architectural grandeur, defined by the imposing Gwanghwamun Gate and the elevated Gyeonghoeru Pavilion set over an artificial pond. The daily Changing of the Guard ceremony remains a major draw, offering a rhythmic, colorful display of traditional military pageantry. Visitors often wander the expansive grounds in rented hanbok—a nod to the past that also grants free admission—navigating between throne halls and quiet rear gardens. It is a massive, living museum that anchors the city’s modern skyline with deep historical roots.
