What is the name of the mansion explored in the original Resident Evil?

The mansion explored in the original Resident Evil is called Spencer Mansion.

The estate stands in the Arklay Mountains outside Raccoon City and serves as the game’s central setting. It is named after Oswell E. Spencer, one of Umbrella Corporation’s founders and the mansion’s owner.

S.T.A.R.S. members enter the building while investigating the disappearance of Bravo Team. Inside, they encounter zombies, mutated creatures, locked rooms, hidden laboratories, and evidence of Umbrella’s biological research.

A common mix-up is calling the location simply the Arklay Mansion. The Arklay Mountains are the wider region, while Spencer Mansion is the specific building. The mansion’s elaborate architecture and interconnected rooms became a defining visual feature of the original game.
