The Boyle Mansion is a building in Dunwall owned by the Boyle family. It is located on Greasely Boulevard in the wealthy and opulent Estate District. While much of the area surrounding the mansion is abandoned and filled with weepers, the City Watch has been ordered to fortify the area (likely by Hiram Burrows, due to his affair with Lady Boyle), bringing in Officers and tallboys.
Built on the banks of an estuary, the mansion was originally the home of a High Overseer before being purchased by the Boyle family. It is not known when the mansion passed to the Boyles; however, due to the discovery of valuable crystal deposits (used in the making of rat lamps, a special type of anti-plague security) on Boyle land, the sisters have been able to maintain and modify the building for their own purposes.
On the mansion's first floor are a vast ballroom replete with ornate furnishings; a foyer with gilded walls; a smoking room; and a music room. In the basement, there are the servants' quarters, a kitchen, and a large wine cellar containing a vault and river access via the sewers. Below that is a large vault which houses the skeleton of an unnaturally large whale gifted by Hiram Burrows to Waverly Boyle. On the upper level are the quarters of the Boyle sisters (two on one side of the great hall, one on the other side), an exhibition hall featuring urns and a Sokolov painting of Vera Moray.
In both of the two bedrooms that share the same side of the hall, there is a bellpull by the bed. Use either bellpull to open a hatch in the bedroom ceiling. The hatches lead to a hidden attic with a chest containing gold ingots, and the Boyle Cameo.
Outside of the mansion is the courtyard decked out in balloon-like lamps, where Lady Boyle holds garden parties. A small tower serves as a residence for the guards.
- The Heart says that Lydia Boyle went from room to room, intentionally "desecrating" the building after the family purchased it from the High Overseer.
