The Spencer Mansion appears in the Resident Evil Movie and Resident Evil. In the movie it is used as the emergency point and doesn't serve a significant a mount as most of the movie is in The Hive. Though in Resident Evil the game is completely based in the mansion and it's surrounding areas.
 Surrounding Areas
Around the Mansion there is a gardened courtyard which further leads a path to a reservoir then a cemetery then eventually the little house of the monster known as Lisa Trevor. There is a guardhouse to the rear of the mansion which serves as a home for the staff of the mansion and a concealing area for the aqua ring. The other notable location which is well known is the reflecting pool which serves as a guard to the further down laboratories.
 The Incident
The research and experimenting in the mansion occurred until the May of 1998 when the T-Virus managed to leak its way throughout the whole mansion. This managed to affect everything which was throughout the mansion. All the workers and staff were turned into zombies and all of the test experiments were turned into whatever they became after the T-Virus managed to infect their bodies. This was able to be known seeing as the Cerberus Dogs managed to get out of the mansion and wreak havoc throughout the entire Arklay Forest. As well as zombies who attacked the by passers and the people who were exploring the forest.
