Fireworks lit up the sky at the Wonsan Kalma resort in Kangwon province on North Korea's east coast during its grand opening on 24/6.

North Korean media described it as a "world-class" coastal tourist city, "where over 400 artistically designed buildings line the white sand beach, creating a perfect combination." North Korea's population is approximately 26.5 million.

Wonsan Kalma has about 50 luxury hotels, offering approximately 7,000 rooms.

The project was launched in 2014. Kim Jong-un aims to transform the coastal city of Wonsan from a local destination into a multi-billion dollar tourist hotspot.

Resort amenities include indoor and outdoor water parks with colorful slides, a mini-golf course, a cinema, a theater, an arcade, restaurants serving local and international cuisine, a shopping center, a stadium, and other entertainment facilities.

The beach area offers swimming, sunbathing, and recreational activities.
