6. Majori Primary School Sports Hall
Year Opened: 2008
Location: Jurmala, Latvia
This small arena outside of the Latvian capital of Riga earns a place on this list despite being a multifunctional facility thanks to it’s unique design. The Majori Primary School Sports Hall is another ode to minimalism and nature as it resembles chunks of amber that wash up on the Baltic coast. The structure uses varying heights as to not full interfere with the surroundings as well as enclose an existing shed from the neighboring closed school. The building is covered in polycarbonate that’s sixty percent transparent allowing outsiders to watch the game. The hall also illuminates the surrounding area thanks to the interior lighting and bright ice.
