Fortress is the second studio album by Canadian band Protest the Hero which was released on January 29, 2008 on Vagrant Records in the US and Underground Operations in Canada.

Another video, this one for "Palms Read", began filming in September[6] under director Sean Michael Turrell, and was released in late October.

Fortress, like its predecessor Kezia, achieved universal acclaim with high regards from many major publications, receiving a comprehensive score of 86 on Metacritic making it the 12th best reviewed album on the site for 2008.

[19] Tyler Patrick Munro of SputnikMusic states: "The album improves on everything established on Kezia (right down to the much more natural sounding piano codas), and it does so without the sometimes blatant repetition of its predecessor."

He cites the track "Bone Marrow," stating: "While 'Bone Marrow' places more emphasis on the underpinning synths of the first two tracks, its heavy orchestration still takes a backseat to its varying structure, which fluidly transits from hyper-melodic up-tempo to ball-crushing gutturals and chugged syncopation, all of which are made twice as effective by the interwoven bass slapping," and compares the style of the opener "Bloodmeat" to the dissonance of The Dillinger Escape Plan and Converge.

[20] John A. Hanson, also reviewing for Sputnikmusic, writes: "[W]ith Fortress, Protest the Hero have almost shed all of their past imperfections and crafted something really special," going on to praise frontman Rody Walker for his vocal range and improvement since Kezia.

[21] Katherine Fulton of Allmusic praised the band for their originality and boldness, writing: "More risks are taken, from the nearly hidden horns on 'The Dissentience' to the shimmering piano solo at the beginning of 'Sequoia Throne' and the playful interlude that bridges 'Palms Read' and 'Limb from Limb,'" though she ultimately criticized the album's "frantic" pace.
