Poland is an unlikely destination for diving fanatics.
With roughly 400 km of frigid coastline on the Baltic Sea, you'll find no coral reefs or schools of rainbow fish here.
You will however find the world's deepest diving pool at an unassuming hotel in Mszczonow near Warsaw.
The DeepSpot divingpool is 45 metres deep and filled with 8000 cubic metres of water. It's an artificial ocean around 27 times the size of an Olympic pool.
In short it's the perfect sport for scuba enthusiasts or new learners.
The tiled walls and overhangs provide plenty of challenges to explore, and in them you'll find windows looking out from the hotel conference rooms and suites.
An unusual feature is the glass tunnel crossing through the middle of the pool, allowing observers to experience the depths without donning an aqualung.
