Brutal Assault is an extreme metal open-air music festival that takes place in an 18th-century army fortress (Josefov Fortress) in Jaroměř, Czech Republic. It takes place each August, traditionally on a Thursday, Friday and Saturday, at the beginning of the month. The festival was started in 1996, originally featuring mostly grindcore music. For many years, it was a small show with mainly local Czech and Slovak bands performing. It changed location several times and grew into a major event in 2006, when over 7,000 people came to that year's event in Svojšice. After moving to Josefov, the attendances grew further to 15,000 in 2012. Brutal Assault currently operates a two-stage system. The festival motto is: "Against violence and intolerance".
