Unless you’re a professional scuba-diver or have spent your life studying the depths of the ocean, there are probably a lot of weird things existing sub-aquatically that you wouldn’t think could be there. Sure, there are lots of bizarre sea animals that we don’t know much about but, but what about the random objects and even buildings? Here are 5 of the strangest things you can find underwater today.

1. Underwater Museum of Art, Florida
Located off the coast of South Walton in Florida, the Underwater Museum of Art (or UMA for short) officially had its underwater inauguration in May of 2019 when a total of seven underwater abstract sculptures by seven different artists were lowered into the Gulf of Mexico. The museum is only accessible in person by strapping on some diving gear. It was created for the purpose of becoming part of the marine habitat and expanding opportunities for marine education, as well as creative and economic opportunities. It’s also just cool to look at, with schools of fish making themselves at home in-and-around the sculptures pretty immediately after the installations were implemented.

2. Yonaguni Underwater Pyramid, Japan
Experts can’t quite seem to agree on whether these mysterious ruins are from a long-lost city, or if they aren’t man-made at all but merely a strange geological phenomenon. Discovered in 1995 off the coast of Japan by a meandering deep-sea diver, the colossal blocks look as though they are ridged purposefully into the side of a mountain. Not only that, but they seem to form unnatural archways and hard right angles that aren’t common in other natural undersea formations. The controversy remains, but for now it’s just fun to imagine another lost city of Atlantis.

3. Museo Atlántico Lanzarote, Playa Blanca
Consisting of 10 different groups of statues designed by artist Jason deCaires Taylor, these detailed underwater sculptures are located 12-15 metres below ocean level at Playa Blanca off the coast of Coloradas Bay. The exhibition was completed in 2016 and at the time it was Europe’s first underwater art gallery. The models used for the figures were actually residents of Lanzarote and the entire piece was built to draw attention to environmental awareness, as well as doubling as a large artificial reef. There are plenty of diving excursions available to view the beautiful and eerie community down below and it is a popular sightseeing and tourist spot.

4. The Roopkund Lake Skeletons, India
No, it’s not another art exhibit. A series of up to 800 skeletons, some that have been dated back to roughly 850 AD, mysteriously show themselves once every year – when the lake they reside in thaws. Located deep in the Himalayan mountains, the appropriately nicknamed “skeleton lake” is full of up to 800 skeletons from groups of past potential travellers, although no one really knows. Fascinatingly, archaeologists have determined that some of the groups met their demise up to 1000 years apart from each other leaving scientists stumped as to where they came from or how they eventually died.

5. Nymphas Show Bar, Israel
This since-closed adult entertainment establishment was once the only underwater bar in the world. Abandoned in 2012, the Nymphas Show Bar in Eilat, Israel was purposefully constructed 16 feet below sea level in order to give customers a full 180-degree view of the surrounding ocean scenery. Nobody really knows why it was abandoned, perhaps people were a bit too freaked out about partying at the bottom of the ocean. Whatever the reason, the rusty mossy structure still stands and is definitely curious looking.
