Gyeongju is a small city 50 miles north of Busan, known as the "Museum Without Walls" due to its incredible wealth of historic treasures. This was the capital of the powerful Silla Kingdom which ruled most of the Korean peninsula for nearly 1000 years (57 BC – 935 AD) and is without a doubt the most rewarding excursion you can make from Busan.
We hadn't even discussed it with each other, it was just understood. An unspoken contract between me and Jürgen, sealed the very moment we learned of its existence: the first place we would visit in Busan, before any temples or museums or beaches, was going to be Shinsegae Centum City -- the world's largest department store. That title is Guinness-certified and uncontested. Shinsegae is three times the size of Macy's, which was the previous record-holder.
