From Passion to Geek Culture Leader in Luxembourg

LGX, short for Luxembourg Geek Xperience, is the largest geek convention in Luxembourg, gathering thousands of visitors each year around the worlds of gaming, manga, cosplay, pop culture, tech, science fiction, and much more.

Originally founded as Luxembourg Gaming Xperience, the event was initially dedicated to e-sports and the video game world. Driven by public enthusiasm and the lack of similar events in the Grand Duchy, LGX quickly evolved into a must-attend gathering for the entire geek culture, never losing its original passion or commitment to excellence.

What sets LGX apart is the commitment to going deep. When we talk about cosplay, we invite world-class talents like Kamui Cosplay. When we discuss gaming, we’ve welcomed major figures such as SK Gaming, Daxe (FIFA 17 World Champion), Teeqzy, Mushway, and even Kameto at his prime. When we open up to Asian universes, film and series, or pop culture, we do it with ambition and a true attention to detail.

LGX is an immersive experience, a unifying event, a stage for talents, and a bridge between generations.
