Interesting facts about Yaren District:

- Unofficial Capital: Yaren District serves as the de facto capital of Nauru, making it one of the very few countries in the world with no official designated capital city.

- Runway Intersection: The district is home to Nauru International Airport, where the main runway cuts right across the narrow landmass so closely that the island’s primary coastal road has to be blocked off with gates whenever an airplane lands or takes off.

- Subterranean Waters: The area features the Moqua Caves system, an underground limestone cavern network that houses a hidden freshwater lake which historically served as a vital water source for the local community.
