The second in importance house of worship in Ethiopia — the Holy Trinity Cathedral — contains the tombs of the Former Emperor Haile Selassie and his wife. Many more prominent figures of the country's history are buried on its compounds. The building itself is a curious mix of international styles.

The extraordinary rock formations and caves of Al-Qara are one of the most prominent landmarks in the Al Ahsa region and are well worth a dedicated day trip. Exploring the maze-like caves is a pleasant experience year-round; the caves remain cool during the summer and warm in the winter. The mountaintop offers unobstructed views of the lush palm oasis below. According to local legend, these caves are associated with the story of Judas Iscariot, who is said to have ended his life here after the biblical betrayal.

A hidden door inside leads into the crypt, where several Ethiopian royals are buried, along with Emperor Menelik himself. The marble tombs are a stunning discovery in themselves, but the real kicker is an original painting by Michelangelo also on display here. Come with a guide to get the full experience.

Just next to Lu Xun Park, you'll find Qingdao Underwater World, also known as the Marine Products Museum. Covering 7,300 square metres, this aquatic wonderland houses an impressive 4,000 tonnes of water and showcases a diverse range of marine life. It's the kind of place where you can explore everything from colourful fish to fascinating sea creatures, all under one roof.
