Walltopia was founded in 1996 as a manufacturer of artificial climbing walls and holds. Now the company is global leader in its field, supplying its products to every country in the world where climbing is popular – including all West European countries, USA, Canada, Japan, Australia,et. Starting with just 5 people, the company now employs over 300 people working in the areas of design, engineering, manufacturing and installing of the climbing walls.

The next step in Walltopia’s development is to create sports and culture centers for active people. The first Collider Activity Center will be in Sofia. Its design is the task of the open international architectural competition of Walltopia. The aim of the Collider Activity Center is to gather in one place all activities of the dynamic people; to gather the sportsmen with the artists, the economists with the dancers and actors, the experienced with the dreamers. If you would like to be part of this idea, take part in the architectural competition of Walltopia!
