A poster-sized periodic table of the elements hangs in most science classrooms. But the University of Murcia in Spain has gone one giant step further. The school’s chemistry department turned the side of a building into a huge periodic table. It’s the largest in the world.

The 150 square meter (1,600 square foot) table is made up of 118 colorful square panels—one for each element on the periodic table, including four newly named elements added last year.

Pedro Lozano Rodriguez, the dean of the chemistry department, hopes the new larger-than-life sight will help people appreciate chemistry. “Everything that surrounds us is formed by the elements contained in this periodic table,” he says.
