CASTRUM was founded in 1994. The early days marked three demo releases on the band's account: "Burial of the Affection", "Flames by Impiety" & "Pleasure in the Deeds of Horror", all of them came out in 1996.

In 1999 the band signed a deal with Ukrainian underground label Metal Force Records. The first result of this alliance was an MC release of the above mentioned demos unleashed under the banner of "The Leading Spirit of Medieval Tortures", which was followed by the band's debut album "Hatenourisher" in the fall of 2000.

Shortly after this tape release the band signed a deal with Canadian Bloodbucket Productions. Thus three full-length CDs were successfully spread into the underground masses, namely "Hatenourisher" in 2001, "Mysterious Yet Unwearied" in 2002 and "Phenomenonsense" in 2006.

After a few member changes the line-up of CASTRUM finally became stable in 2012. It consists of the relentless forces of Cornelius (vocals/guitar), Victor (bass) & Eugene (drums).

To celebrate the band's 20th anniversary a compilation CD titled as "MediEvaluation" was released in 2014 by the band's long-time label Bloodbucket Productions!

The band's fourth full-length album is still in process. It is going to be the fiercest and most sophisticated one! So watch out!!!
