D-Cube City (Korean: 디큐브시티) is a mega-complex in Seoul, Korea, which comprises department stores, office space, a park, an art center, a theatre, a hotel, restaurants, a theme park, and private residences.

[2] D-Cube City's six acres of parks, plazas, and gardens are spread across the structure's stepped roofs.

Large atriums house many species of plants as well as internal water features and a six story waterfall.

[4][5][6][7][8] During construction, an endangered species of frog, Kaloula borealis was found on the site.

Daeseong Industries had around 400 billion won in loans until 2007, but at the end of 2011, its debt rose to 278.8 trillion won due to the repayment of the D-CUBE City Construction Project Financing (PF) KRW 977 billion.
