Fortress was recorded between April 26 and July 2, 2013 at Studio Barbarosa in Orlando, Florida. The album was written over the three previous years while the band toured, as well as during Alter Bridge's hiatus due to singer Myles Kennedy touring with Slash, guitarist Mark Tremonti releasing his debut solo album All I Was, and drummer Scott Phillips recording with his band Projected.
The album debuted at number 6 on the UK Albums chart, making it the band's highest charting album in the UK to date. It debuted at number 1 in the US, Canada and Sweden on the iTunes rock album chart.
