Sanctuary Spaces is a collection of two digital editions by Doug Foster which derive from large scale installation pieces by the artist. Both works reference Foster's interest in creating transcendental, mesmerising spaces which transform existing structures into gateways to other worlds.

The two works in the collection are extensions of installation pieces by Foster; they are sister works, sharing the same score by UNKLE (J Lavelle, P Clements and J Griffith) as well as thematic and stylistic similarities.

The Heretics' Gate links to Foster's 2010 large scale digital film installation of the same name, which was made in 2010 and was inspired by Dante Alighieri’s Inferno. Originally shown at St Michael's Church in Camden as part of a Daydreaming With... exhibition curated by James Lavelle, the work represents Dante’s entry point into the Sixth Circle of Hell, where non-believers burn for eternity in furnace-like tombs.

Chimera is derived from a large scale digital film installation created for Lazarides' The Minotaur exhibition at The Old Vic Tunnels in 2011. It was inspired by the mysterious process of metamorphosis and by our continuing exploration of the genetic soup in which we all swim.

Both works in the Sanctuary Spaces collection were made in 2019 and are produced in UHD colour with stereo sound and shown as a 9'40" seamless loop.
